Sophia, the marketing manager of the scenic area on the Greek island of Santorini, used to worry about the mountainous piles of paper brochures in the warehouse - every year, 500,000 copies had to be printed, covering 6 languages including English, French, and German. After the peak season passed, the unprinted brochures had to be treated as waste paper, and the wood wasted alone amounted to 30 tons. What was even more annoying was the loudspeakers in the quiet alleys of the blue and white town. The tour guides' shouts drowned out the oarswings of the gondolas, and tourists complained that it "spoiled the vacation feeling". The local environmental protection department even reminded them that the noise was excessive. In fact, not only Santorini, but many overseas scenic spots and museums were also plagued by environmental problems such as paper waste, noise pollution, and equipment obsolescence. However, Yingmi Wireless Guide, from equipment to service, gradually solved these problems one by one.
    As the core product of Hefei Huima Information Technology Co., Ltd., which has been in operation for 15 years, Yingmi Wireless Guide did not use "environmental protection" as a gimmick. From the day it was designed, it incorporated these elements - the body is made of recyclable materials, the battery can last for a whole day without frequent charging, there is no need for paper brochures, and it can reduce noise. It has been used by customers such as Xiamen Gulangyu Island, the British Museum, and Huawei, which are environmentally conscious. Yingmi's confidence lies in "helping overseas tourism and culture industries reduce pollution and increase cleanliness" - it is not just a device that can make sounds, but more like a "little helper" that protects those beautiful landscapes.

I. Environmental Challenges in Overseas Tourism and Culture Preservation, and How Yingmi Solves Them?

When it comes to overseas tourism and cultural preservation, there are three major environmental problems that are particularly troublesome. Yingmi focuses on these issues and thoroughly develops the equipment and services:

1. No need for paper-based guidebooks, reducing deforestation

Overseas tourist attractions and museums print a large number of guidebooks every year. Tourist attractions print guide pages, museums print exhibit descriptions, and enterprises print reception manuals. After the peak season, the unissued guidebooks pile up and take up space. Eventually, they have to be discarded, which is both wasteful and polluting. Sophia once experienced this problem: "Last year during a typhoon, the warehouse leaked, and 100,000 copies of multilingual guidebooks that had just been printed were all soaked and ruined. They could only be hauled away as waste paper. The printing cost alone cost 50,000 euros. It was truly heartbreaking." Moreover, the ink used for printing the guidebooks and the wastewater generated from disposing of the waste paper are invisible pollutants.
Yingmi replaces the paper-based guidebooks with "digital content", fundamentally reducing waste:
The equipment stores all the content for the guides, including the history of the scenic area, details of the exhibits, and the introduction of the enterprise. Tourists can view it using a receiver or scanning a mini-program. No paper is printed at all. Xiamen Gulangyu used Yingmi, and they printed 500,000 fewer guidebooks each year. This resulted in a 30-ton reduction in wood usage and a 120-ton reduction in carbon emissions.
Content updates do not require re-printing. A few clicks in the backend can transfer new content. When the British Museum held the "Special Exhibition of Chinese Song Ceramics", they added explanations for several new exhibits and directly pushed them to the equipment. Unlike before, they no longer had to "rush to print 20,000 new copies overnight", saving both time and being environmentally friendly.
No internet connection is also possible. In remote areas like Iceland's glaciers and African grasslands, tourists can store the content in advance and still understand the information without having to bring paper guidebooks.
"Nowadays, you can no longer see piles of guidebooks like mountains in tourist attractions. Tourists carry the small receivers and explore, which is both lightweight and clean. The local environmental protection department even specially awarded us a plaque for 'Sustainable Tourism Case'. We are so happy."
After using Yingmi in the Venice area, the noise in the narrow alleys dropped from 65 decibels to 40 decibels. "Tourists finally can listen to the boatman singing quietly. Complaints decreased by 80%," said Sophia. When multiple teams visited together, it was not noisy either. Each team used a separate channel, and there was no need to raise the volume to overpower others. When Huawei visited the factory in Dubai to receive suppliers, five teams were visiting simultaneously, speaking in different languages. The workshop was not noisy or chaotic. "Before using the loudspeaker, suppliers always said, 'I can't hear the technical parameters clearly.' After switching to Yingmi, there was no more such problem."
The receiver is ear-mounted, allowing tourists to adjust the volume themselves, and it won't disturb others. On the Icelandic glaciers, tourists wearing the equipment listened to the explanations, neither disturbing other tourists nor startling the wild animals. "Finally, we can quietly view the glaciers."

2. Don't use loudspeakers, maintain a quiet environment

Many overseas tourist attractions have to use high-decibel speakers to ensure that tourists can hear clearly. In the narrow alleys of Venice, the tour guide's shouts overshadow the boat songs; at the viewing platform of the Icelandic glacier, the speaker scared away the nearby Arctic foxes; in the enterprise workshops, the speaker's sound mixed with the machine sounds, and the suppliers couldn't hear the technical parameters clearly. These noises not only bothered the tourists but also violated many countries' environmental regulations.
Yingmi's equipment can "precisely transmit sound" without using loudspeakers:
The SOC digital noise reduction technology is particularly practical. It can filter out 90% of environmental noise. When the tour guide speaks normally, tourists within 10 meters can clearly hear it. There is no need to shout loudly. Venice used it and the noise in the narrow alleys dropped from 65 decibels to 40 decibels. "Tourists finally can listen to the boatman singing quietly. Complaints decreased by 80%."
When multiple teams visit together, it is not noisy either. Each team uses a separate channel, and there is no need to raise the volume to overpower others. When Huawei visited the factory in Dubai to receive suppliers, five teams were visiting simultaneously, speaking in different languages. The workshop was not noisy or chaotic. "Before using the loudspeaker, suppliers always said, 'I can't hear the technical parameters clearly.' After switching to Yingmi, there was no more such problem."
The receiver is ear-mounted, allowing tourists to adjust the volume themselves, and it won't disturb others. On the Icelandic glaciers, tourists wearing the equipment listened to the explanations, neither disturbing other tourists nor startling the wild animals. "Finally, we can quietly view the glaciers."

3. Equipment is durable and energy-efficient, reducing waste

Traditional guide devices have many problems: short battery life, needing to be charged every half day, and consuming a lot of electricity; the body is fragile, and a single drop can break it, and many replacements are needed each year, which also pollutes the environment when disposing of the waste equipment. An overseas museum previously used cheap equipment and "replaced 200 units every year. The discarded equipment piled up in the warehouse. The environmental protection department said it needed professional handling. Just the cost alone was 50,000 euros."
Yingmi put a lot of thought into the durability and energy efficiency of the equipment, aiming to reduce the burden on the environment:
Battery endurance: The PMU lithium batteries used can power the transmitter for 15 hours and the receiver for 8 hours. The equipment doesn't need to be recharged repeatedly throughout the day. A tour guide in the desert area of Dubai said: "From 9 a.m. to 6 p.m., the equipment still had two batteries left. There was no need to carry a power bank and run around, and much less electricity was wasted."
The body is durable and recyclable: The main body is made of recyclable ABS plastic. If it breaks, it can be disassembled for reuse. The outer shell is reinforced with cushioning glue, so it's fine even if it falls from a height of over 1 meter. The Acropolis in Athens, Greece, used Yingmi equipment for 3 years. "Only 5 units needed repair because they were dropped too hard. They were three times more durable than the previous equipment, and a lot of discarded equipment was saved."
Idle time can save electricity: If the equipment is not used for 5 minutes, it will automatically enter a low-power mode, consuming 60% less electricity. When tourists are taking photos or resting, there's no need to waste electricity unnecessarily.

II. Yingmi's "Full Process Environmental Protection": Not only the equipment, but even the services are streamlined

Yingmi's environmental protection is not just about good equipment; it also takes into account the leasing, management, and recycling processes, helping overseas users save both time and resources while being environmentally friendly:

1. Self-service rental and return + batch charging, saving manpower and electricity

Previously, renting equipment required a dedicated person to be on duty, and charging had to be done by plugging in individual devices. With Yingmi's Z50 self-service rental cabinet and batch charging box, these tasks have been made efficient:
Tourists can scan a code to rent equipment, without needing a person to supervise. The scenic area hires fewer staff and reduces carbon emissions from traveling back and forth.
36 or 48-position charging boxes do not require plugging in a bunch of wires. Just put them in and they start charging. They can also be automatically adjusted, saving 40% of electricity compared to individual charging. There's no need to use alcohol swabs to wipe, and much less chemical disinfectants are used.
The rental cabinets have ultraviolet disinfection, and when returning the equipment, it automatically disinfects for 30 minutes. There's no need to use alcohol swabs, and much less chemical disinfectants are used. The manager of Gulangyu Island, Sister Wang, said: "Now there's only one person needed to manage the equipment, while before it required three people. We saved 12,000 yuan in electricity costs each month, and 80% less alcohol was used. It's really worth it."

2. Analyze data to adjust needs, avoiding waste

Many overseas scenic spots failed to understand the needs of tourists, either printing more paper books or purchasing more equipment, which ended up being wasted. Yingmi has a real-time data backend that can help figure out the needs:
You can see which languages tourists prefer, which attractions they stay at for a long time, and the scenic area can adjust the content based on this, without having to print a bunch of books in each language.
You can also see how the equipment is being used, knowing when there will be more people and when to replenish equipment, and which areas have less usage and should not have more equipment placed. Dubai used YingmiMC200 for a certain exhibition and said: "Previously, we bought 100 devices, but in reality, we only used 60. Now, based on the data, the equipment utilization rate reached 90%, and we saved a lot of money."

3. Old equipment can be recycled, not thrown away randomly

To prevent waste from old equipment from polluting the environment, Yingmi set up an old equipment recycling program - for equipment used by overseas users for 5 years, they can apply for free recycling. Professional teams dismantle it, reuse the useful parts, and destroy the unused ones environmentally. Now, it can be recycled in 12 places across Europe, the Middle East, and Asia. "Last year, we collected 500 old devices, and from them, we extracted 200 kilograms of usable metal and disposed of 3 tons of waste equipment," said the colleague in charge of environmental protection at Yingmi.

III. Overseas Environmental Protection Cases: How Much More Convenient Is Yingmi's Use?

Yingmi's environmental protection is not just talk; it has been implemented in many places overseas, bringing real changes everywhere:

1. Gulangyu Island, Xiamen: 120 tons of carbon emissions reduced annually

Gulangyu Island used to print 500,000 paper explanations every year, wasting 30 tons of wood and using loudspeakers. After using Yingmi:
No more paper books, saving 30 tons of wood and 120 tons of carbon emissions;
15 loudspeakers were dismantled, and the noise in the scenic area dropped from 70 decibels to 45 decibels, meeting environmental standards;
Batch charging saved 40% of electricity, and the monthly electricity cost was reduced by 12,000 yuan.
"Now there are no more randomly thrown explanations in the scenic area, and tourists say 'it's more comfortable to visit,' and we have been awarded the 'China Cultural Tourism Low-Carbon Case' and many overseas scenic spots are asking how we did it," Sister Wang said.

2. The British Museum: No paper for special exhibitions

The British Museum used to print 30,000 explanations for special exhibitions each time, and there was a lot of leftover paper after the exhibition. In 2023, the "Chinese Song Dynasty Ceramics Special Exhibition" used YingmiMC200:
All 8 languages of the explanations are stored in the equipment, and tourists can listen by touching, no paper printing is needed;
The recyclable materials used by the equipment are collected at the end of the exhibition and used next time, avoiding waste;
Automatic disinfection and charging, no need to wipe with alcohol swabs, and less electricity is used.
"The environmental department said we reduced 8 tons of carbon emissions this time, and tourists also said 'it's cleaner without paper,' and we plan to use Yingmi for all future special exhibitions," said Jones, the guide department of the museum.

3. Dubai Desert Scenic Area: Enduring in Hot Weather

In Dubai, the summer temperature can reach 45℃. Traditional equipment won't last for even a few hours before breaking down, and batteries need to be replaced frequently, generating a lot of waste batteries. After using Yingmi E8:
The battery can still be used for 8 hours at high temperatures, reducing the need for 100 charging sessions per day and saving 50 kWh of electricity;
The equipment is dust-proof and sand-proof, less prone to damage, and the number of equipment replacements has decreased from 100 units per year to 20 units, reducing the amount of waste batteries by 80%;
Without a speaker, the desert is quiet, allowing tourists to clearly hear the stories of the Bedouin culture.

Conclusion: Environmental protection is not just a slogan; it's about truly protecting those beautiful places

The beautiful scenery and old buildings overseas need to be well protected to last for a long time. Yingmi's wireless audio guide doesn't treat "environmental protection" as a short-term gimmick. From the design of the equipment, service process to final recycling, Yingmi always considers how to minimize pollution - no paper, no disturbing noise, durable equipment, and recyclable old ones.
In the future, Yingmi will continue to focus on environmental protection: developing more energy-efficient chips to make batteries last longer; expanding the scope of recycling old equipment to include more overseas locations; and adding a "carbon footprint statistics" function to let everyone know how much less carbon can be emitted each time they use the equipment. For Yingmi, making the equipment is not just to let people hear the explanations clearly, but also to help overseas tourism and culture protect that purity - whether it's the blue and white town of Santorini or the glaciers of Iceland, there can be less pollution and more purity. This is not some grand slogan; it's something we've always wanted to do and a commitment to those beautiful places.
