One October morning, I got off the all-night train in Mandalay, a city in Myanmar. A rough man came up and offered to show me around. The price he asked was less than I would pay for a bar of chocolate at home. So I climbed into his trishaw(三轮车).

    As he was showing me around, he told me how he had come to the city from his village. He'd earned a degree in mathematics. His dream was to be a teacher. But of course, life is hard here, and so for now, this was the only way he could make a living. Many nights, he told me, he actually slept in his trishaw so he could catch the first visitors off the all-night train.

And very soon, we found that in certain ways, we had so much in common—we were both in our 20s, we were both fascinated by foreign cultures—-that he invited me home.

    So we turned off the wide, crowded streets, and came to rough, wild alleyways(小巷). I really lost my sense of where I was, and realized that I could easily get cheated or something even worse.

    Finally, he stopped and led me into a hut. And then he reached under his bed. Something in me froze. I waited to see what he would pull out. And finally he took out a box. Inside it was every single letter he had ever received from visitors from abroad.

    So when we said goodbye that night, I realized he had also shown me the secret point of travel, which is to go inwardly(向内心)as well as outwardly to places you would never go otherwise, to go into uncertainty, even fear.

    At home, its dangerously easy to think we're on top of things. Out in the world, you are reminded every moment that you're not, and you can't get to the bottom of things, either.

    Mom noticed that something was wrong when I started getting so thirsty. I'd have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I'd drunk the entire container! My mom called my doctor. I then had a few blood tests, and the results were certain — I had diabetes (糖尿病), which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.

    My eating habits had to change in a big way. With diabetes, I can't eat a lot of sugar or carbohydrates (碳水化合物). I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin (注射胰岛素) before the meal to help my body process the food. Also, I test my blood-sugar level often. I'm always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn't keep me out of gym class or off the basketball court — I just keep some juice boxes around to boost my blood sugar if I need to.

    It's a lot of work and not a lot of fun to keep track of everything, but I've gotten used to my new habits. I was a little scared at first because I wasn't sure how my life would change. Once I knew what I needed to do, though, it wasn't a big deal. My life is different now from what it was before, but it has become completely regular to me.

    A killer whale(虎鲸) that can copy words such as “hello” and “bye-bye” is thought to be the first of its kind to copy human speech.

    The female killer whale learned to “speak” some human words by copying a trainer at a park in France. The animal's ability includes speaking the name “Amy” and “one, two, three”.

    Whales and dolphins are among the few animals except humans that can learn to produce a sound just by hearing it. “It is not often seen,” said Dr Josep Call, a co-researcher on the study. “Humans are good at it…Interestingly, the animals that can do best are marine mammals(海洋哺乳动物).” The researchers start to find out whether killer whales could learn new words by copying others. They studied a female named Wikie at Marineland Aquarium in Antibes, France. She was taught to speak human words.

    Dr Jose Abramson, a co-researcher on the study, said basic “conversations” with Wikie may one day be possible. He said,” It has been done before with a famous grey parrot and dolphins using American sign language(手势语).” However, he said they have to be careful about introducing human ideas on animals, as there is more to learn by trying to understand the natural way each kind communicates in its own environment. Wikie made sounds in water, which may be quite different.

    Dr Alex Thornton, senior speaker at the University of Exeter, said they still don't fully understand why some animals learn to copy. Some animals copy sounds to attract possible partners, while others copy sounds to become a member of a group. “Some whales, for example, learn their calls from one another to mark them out as members of their social group,” said Dr Thornton, who doesn't join in the research.

    When we are young we are taught that it's wrong to lie and we should always tell the truth. Unfortunately, most children lie even if they're told not to. Research carried out at the Institute of Child Study at Toronto University has shown that this might not be such a bad thing. Apparently (显然地), children who tell lies when they're two years old have a good chance of becoming successful adults (成年人).

    According to the research, at the age of two, 20 percent of children lie. At the age of three, 50 percent lie, and at four almost 90 percent lie. By the age of 12 almost every child tells lies.

    Lying needs much brain work. And the better the lie is, the more work the brain has to do. By training the brain early, researchers believe children will be able to think more clearly when they are adults.

    Recent research, carried out by the Science Museum in London, has shown some interesting facts about the way we lie as adults. According to the research, the average British man tells three lies every day, that's over 1,000 lies a year. However, the average woman apparently only lies twice a day.

    Most people think women are better liars (说谎者) than men although in fact they tell fewer lies. Popular women's lies include 'Nothing's wrong, I'm fine', 'I don't know where it is, I haven't touched it', and 'It wasn't that expensive'.

    Some people say you can lie as long as it's a white lie. A white lie is a lie told to avoid hurting someone's feelings. One of the most common lies for both men and women is 'It's just what I've always wanted', said after opening a present from their partner.

    When HarmonyOs, the Chinese self-developed operating system for Huawei mobile devices, was released on Aug 9, it quickly became a hot topic on social media. Many believe it not only represents the rise of the country as a tech power, but also shows respect to classical Chinese culture by naming the system "Hongmcng" in Chinese.

    "Hongmeng" is a classical word from Zhuangzi. In the ancient times of Chinese legend and myths (神话),"Hongmeng" was used to describe the original state of the universe before matter existed. For HarmonyOS, "Hongmeng" indicates the developers' aim to make an innovative operating system, unlike any other.

    Besides "Hongmeng'", Hunwei has also registered many of its products under the names of legendary creatures from Chinese myths. For example, the company's Kirin mobile chip got its name after a lucky monster called "Qilin". And its server chip is calked "Kunpeng", a creature that changed from a fish into a giant bird.

    Many Chinese Internet users and media have praised Huawei's use of these names," as they stand for Chinese wisdom and ancient people's imagination and spirit of exploration", Global Times noted.

    In fact, Huawei is not alone in using traditional culture for modern ventures. Ne Zha, the new film, also portrays traditional culture in a modern context. The movie is loosely based on the well-known work of classical Chinese myth The Investiture of the Gods. Earlier this month it became the biggest animated movie in China and was called "the glory of domestic anime (国产动漫)".

    Indeed, the long history and splendid classic works have given China a profound culture. Myths and legends are the creative works of tremendous imagination. As Global Times put it, today by revisiting a modern context, "ancient myths has the power to inspire imagination in young people". After all, imagination is the beginning of creation.
