The World’s Tropical Fruit Window in Qionghai, Hainan, houses over 400 kinds of exotic fruits from all over the world – the mysterious fruit that can sweeten lemons, the “tree-top Haagen-Dazs” with flesh like ice cream, and the durian honey that looks like a pineapple but is full of honey fragrance. Each fruit is wrapped in its own origin story and little secrets. Just before 2025, this “fruit secret land” was constantly troubled by the issue of explanations: when tour guide Xiao Zhang led the group, he always had to shout with all his might to introduce, but the tourists in the back row still couldn’t make out the difference between “durian honey and jackfruit honey”. Foreign tourists stared at the fruit for a long time but still couldn’t figure out what it was called or what was special about it. On weekends, when the team gets larger, the voices of several groups of people’s explanations blend together, making it as chaotic as a vegetable market. Even finding a lost elderly person requires Shouting through a loudspeaker in the orchard. It was not until the Yingmi E8 tour guide system entered the park that all these annoying issues were completely resolved. Now, visitors wear lightweight ear-hanging headphones and follow the clear explanations as they wander through the passion fruit corridor and star fruit maze. The fragrance of the fruits is mixed with the sounds of stories, and even children who used to run around can listen quietly for a long time.
I. The “Sweet Troubles” of the Fruit Window: Three Puzzles Block the Story of Fruits
As a distinctive area of tropical agriculture in Hainan, the World Tropical Fruit Window was supposed to let the story of each fruit be heard by more people. Before the E8 was installed, the people in the scenic area and the tour guides had to deal with three unavoidable troubles every day.
1. It’s too noisy outdoors: Explaining is tiring for the voice
The orchard covers an area of 500 mu, with fruit trees everywhere. When the wind blows, the leaves rustle. The irrigation machine hums during the day. Coupled with the conversations of tourists, the tour guide’s voice is “washed away” as soon as it comes out. Xiao Zhang talked to us about the past days, full of helplessness: “When leading a tour group to the ice cream fruit tree, I had to raise my voice to my throat and say, ‘This fruit is from South America and tastes like melted Haagen-Dazs.’ But the tourists in the back row would still come over and ask, ‘Where did you just say it came from?'” “;” When talking about durian honey, it is repeatedly said that “its seed can be cooked and eaten, and it is more fragrant than chestnuts”, but when the wind blows, some people still remember it as “the seed of the jackfruit is edible”. By the end of the day, my voice was so hoarse that even swallowing saliva hurt, and I was always afraid that the tourists didn’t understand the key information.
It’s even worse on rainy days. Tourists all gather in groups with umbrellas, making it even harder for the sound to reach far. When arriving at the relatively enclosed small space of the jam workshop, the explanations of several teams collided with each other. Tourists could only “pick and choose” to listen to in the chaos. Many people joked after visiting, “I didn’t hear anything clearly.”
2. Tourists are too diverse: Traditional explanations can’t keep up
The people who come to the orchard are of all kinds and their demands vary greatly: Parents with children hope that their kids can learn while playing, but how can the children sit still? I want to run away after hearing just a couple of sentences. Foreigners from Europe, America and Southeast Asia are particularly curious about the stories of tropical fruits. However, they can’t understand a single word of the Chinese explanation and can only take pictures of the fruits. They even miss the most interesting point like “The mystery fruit can make lemons sweeter”. There were also agricultural experts who came for an inspection, wanting to know the grafting technique of durian honey and the planting cycle of the mystery fruit. However, the tour guide only had a set of “general explanations” and couldn’t explain the professional details.
The operations director also sighed when talking about the previous remedial measures: “We tried putting up bilingual signs in Chinese and English beside the fruit trees, but the old man had poor eyesight and couldn’t see them clearly even when he got close.” We have arranged bilingual tour guides, but during the peak tourist season, when three or four foreign groups come at the same time, there simply aren’t enough guides – in the end, either the tourists find it boring or we spend money but get nothing done.”
3. Too many teams and lost tourists: Chaotic reception and safety concerns
The scenic area is becoming increasingly famous, and the number of groups it receives on weekends and holidays often exceeds 20. However, traditional tour guides have only a few channels. When multiple teams use them simultaneously, a series of sounds on each channel can cause confusion. Just as one team was talking about “the taste magic of the miracle fruit”, another team suddenly inserted “The steps to make jam from passion fruit”. Tourists were confused and the tour guide had to stop and explain again. The originally one-hour visiting route often extended to one and a half hours, and the reception efficiency simply couldn’t be improved.
What is even more heart-wrenching is the “search for the person”. The star fruit maze and passion fruit corridor in the orchard have their branches intertwined, making it very easy for the elderly and children to lose track of the team. In the past, there was no choice but to have the staff carry walkie-talkies and search the orchard in a “carpet-like” manner. Last time, an elderly person got lost in the maze, and it took the staff nearly 20 minutes to find him. The family members were so anxious that they burst into tears, and the visits of other tourists were also delayed. Such incidents made the operation team feel both guilty and anxious.
II. Yingmi E8: Make the story of the fruit clear and understandable
Learning about the troubles in the orchard, the Yingmi team did not just bring a general device over. Instead, they had the staff stay in the orchard for several days to figure out which area was the nozzest, which type of tourists were the most numerous, and the peak hours for team receptions. Finally, they customized a plan centered on E8. Each function precisely hits the previous pain point.
1. Anti-interference + strong noise reduction: Even in the noisiest environment, the sound can remain clear and refreshing
The most satisfying aspect of E8 for tour guides is that it is not afraid of noise. The staff explained to us that this set of equipment uses U-band high-frequency radio waves of 860MHz-870MHz and also adds 4G FSK signal modulation technology. To put it simply, it has opened up a “dedicated lane” for the audio guide. No matter how strong the mobile phone signal beside it is or how noisy the irrigation machine is, its signal will not be squeezed or interfered with. Moreover, it features SOC embedded integrated digital noise reduction, which can automatically filter out useless noises such as wind blowing and bird chirping, leaving only the tour guide’s voice and pre-stored stories.
Now, when Xiao Zhang leads a tour group, he no longer needs to shout: “I put the E8 transmitter in my pocket and the lapel microphone on my collar. At a normal speaking volume, tourists 30 meters away can hear me clearly, as if I were chatting in their ears.” Last time I led a tour group to the durian honey planting area, the irrigation machine beside was running, but the tourists still heard clearly, “Its flesh is softer and sweeter than that of the jackfruit.” No one came over to ask again.
What’s even more considerate is that each pair of headphones can adjust the volume – the elderly can turn up the volume, and children can turn it down to avoid harshness. There’s no need to listen to the same volume uniformly anymore.
2. Interaction + Multiple languages: Parent-child fun, foreigners can understand, and all needs are met
To meet the diverse needs of different tourists, E8 has specially created three “ways of playing” :
For active children, it has an “interactive Q&A” function. When arriving at the miracle Fruit experience area, as soon as the tour guide triggers the transmitter, a question pops up in the tourists’ headphones: “Which fruit should I eat to make the lemon sweeter?” ” Children can answer questions by pressing the quick response button on the headphones. If the answers are correct, cheerful sound effects will be played. Later, the scenic area found that with this function, children’s attention was much more concentrated. After the visit, they could even retell the “secret of the miracle Fruit” to their parents, and the retention rate was 50% higher than before.
For foreigners, the E8 transmitter supports customization in 8 languages – English, Japanese and Thai can all be installed, and it can also pre-store 9,999 segments of explanation content. For instance, when visiting the ice cream and fruit area, foreign tourists can listen to the English explanations by wearing headphones. “This fruit is called ‘ice cream fruit’—it’s native to South America, and its flesh is as smooth as melted ice cream. (this fruit is called “ice cream fruit”, native to South America, with flesh as smooth as melted ice cream) When arriving at the jam workshop, a Thai language guide will explain in detail the “steps for making passion fruit jam”. Once, a Thai tourist listened to it and even asked the staff for the recipe, saying, “I’m going to make it for my family when I get home.”
For agricultural experts, the E8 can also be connected to a mobile phone or tablet. The tour guide can store professional content such as “durian honey grafting technology” and “miracle fruit growth cycle” in advance. The expert can listen clearly with headphones on, without having to take notes around the tour guide or worry about missing key data.
3. Multi-channel + location-based: Team reception is faster, and there’s no need to shout when looking for people
E8 has 200 independent channels. Even if 20 teams are strolling around the park at the same time, as long as the channels are allocated in advance, their respective explanations won’t get mixed up. The scenic area later calculated that after using E8, the daily group reception volume increased from 15 groups to 21 groups, a 40% increase. Neither tour guides nor tourists had to “wait for channels” anymore.
More convenient is “automatic channel following”
Tourists only need to press the SET button to turn on their headphones, and they will automatically search for signals from nearby transmitters and connect to them. In the past, when changing teams or regions, I had to manually adjust the channel. If I wasn’t careful, I would adjust it wrongly, and my ears would be filled with noise. Now, there’s no need to do anything. Just walk from the passion fruit corridor to the star fruit maze. With the guide’s transmitter, the headphones can automatically connect to the new channel in just three seconds. Even the elderly can use it.
The most effective solution to the problem is the “positioning function
Each earphone can be located in real time. Once a tourist gets lost, the staff can click on the system in the background and see the location of the earphones. Last time, an elderly person got lost in the star fruit maze. The staff checked the location and found him in just three minutes. The family members held our hands and said, “We used to be always afraid that the elderly would get lost. Now that they are wearing this pair of headphones, we feel much more at ease when visiting the park.”
What is particularly practical is the accompanying contact-type charging box
The 36-bit or 48-bit design allows you to charge the headphones simply by placing them in the slot. It also comes with ultraviolet disinfection, so you don’t have to worry about unhygienic use by tourists. The box is made of metal and has EVA shock-absorbing cotton inside. The headphones won’t get damaged or damp when placed inside. The scenic area has been using it for more than half a year, and the loss rate of the headphones is less than 1%. The operation director said with a smile, “Tourists are all busy wearing headphones to listen to stories, take pictures of fruits and post them on Moments. They have no time to lose their equipment at all.”
Iii. Not Only Solving Problems: E8 Adds new vitality to Orchards
After E8 entered the orchard, not only were the previous troubles solved, but also the experience and reputation of the orchard were enhanced.
At the passion fruit corridor, the tour guide will play the environmental sound effects of the tropical rainforest through E8 – the clear chirping of birds and the gurgling sound of flowing water will come out of the headphones. Tourists will unconsciously slow down their steps, and even their conversations will turn into soft whispers. In the past, tourists walked loudly and occasionally knocked over unripe fruits. Now, the loss rate of fruit trees has dropped significantly.
The number of overseas tourists has also increased. In the past, there was at most one foreigner among ten tourists, but now it accounts for a quarter. Many travel agencies in Southeast Asia even list this place as a “must-visit attraction in Hainan”. Once I met a tourist from Singapore. She said, “Before, when I went to other tropical orchards, I couldn’t understand the Chinese explanations and could only watch for fun.” This time, listening to the explanation in English, I finally understood why the miracle fruit can change the sense of taste. I also learned to make a salad with passion fruit. I’m going to recommend it to my friends when I get back.
What moved the operation team even more was the “active promotion” by tourists – nowadays, when visiting the park, one can always see people wearing E8 headphones, listening to explanations while shooting videos of the fruits, and even Posting “The story of the ice cream fruit” and “the little Experiment of the mysterious fruit” on social media platforms, which has helped the scenic area do free promotion in an intangible way. The operations director said, “We have been growing rare and precious fruits for ten years and have always wanted more people to know their stories.” E8 is like giving each fruit a “mouth”, allowing them to “talk” to tourists. This is much more effective than advertising ourselves.
Conclusion: Let the story of every fruit be gently heard
Now, when you go to the Window of Tropical Fruits in the World, you can no longer hear the tour guide’s shouts. Some people were answering questions in front of the miracle fruit with headphones on, and laughter filled the orchard. Someone was looking at the ice cream fruit, listening to the story of its origin in South America, their eyes brimming with curiosity. The foreigners, wearing headphones, chatted with their companions in their native language about “How to grow this fruit” and “Can we buy it when we get back?”
Those fruits remain the same, but because of E8, their stories have finally been heard and remembered by more people. Yingmi always say that what they want to do is not “sell equipment”, but help every place tell the stories it should tell well. Looking at the scene before me, I truly feel that this statement is not an exaggeration – good technology is never cold and lifeless. It should be like the fragrance of fruits in an orchard, making people feel comfortable and warm, and allowing every encounter to be “as if” there. If you have such needs, please contact the Yingmi team.
