When I was in Grade 8, I had a heated argument（争吵）with my classmate, Tony. I have forgotten what the argument was about, but I have never forgotten the lesson I learned that day.

I believed that I was right and he was wrong, and Tony believed that I was wrong and he was right. Our teacher, a kind and smart lady, decided to teach us a lesson. She brought us to the front of the class and placed him on one side of her desk and me on the other. In the middle of her desk was a large and round object. I could clearly see that it was black. The teacher asked us what color the object was. “White,” Tony answered. I couldn’t believe he said the object was white! “Clearly, it was black!” Another argument started between Tony and me, this time about the color of the object.

The teacher told me to go and stand where Tony was standing and told him to go and stand where I was standing. We changed places, and now she asked me what color the object was. I had to answer, “White.” It was an object with two differently colored sides from his side it was white, while from my side it was black. “Boys, now, what do you say?” The teacher smiled at us. Tony has been my best friend ever since.

My teacher taught me a very important lesson that day: When you disagree with others, you’d better be in their shoes. That will help you look at the situation through their eyes, and truly understand their ideas and ways of thinking.

Wukong, Tiangong, Tianwen…Do you know where the names of Chinese space programs come from?

Wukong, the Dark Matter Particle Explorer satellite（暗物质粒子探测卫星）, is named after Chinese superhero Monkey King. According to Journey to the West, Monkey King has a pair of sharp eyes which can tell the difference between good and evil. The Wukong satellite is just as sharp-eyed as Monkey King to help scientists search for dark matter in space.

The name of the space station, Tiangong, means “Heavenly Palace”. In Chinese myths, this is the home of Tian Di. Now Tiangong Space Station is a home for Chinese astronauts in space. And China welcomes foreign astronauts to Tiangong so that they can work together.

Tianwen, China’s Mars missions（任务）, gets its name from the poem Tianwen by Qu Yuan. Qu Yuan is a well-known poet from ancient China. In Tianwen, he had the questions about the sky, stars, nature, myths and the real world, showing his hunger for truth. Perhaps the Tianwen missions will end up answering some of Qu Yuan’s questions.

If you look into more names of Chinese space programs, you will find that they all have beautiful meanings. We, the Chinese people, have a long-cherished（珍藏已久的）space dream. So the naming of Chinese space programs is taken very seriously.

Because of COVID-19, people may have bad feelings, such as sadness, anxiety（焦虑）and fear. Helping yourself and your family members keep a positive attitude will be very important for everyone to get through this difficult period. Below are four ways to keep your body and mind strong.

Recognize and accept your feelings.

When you stay at home for a long time, it is normal to feel upset or anxious. The first step is to recognize and accept these feelings. It means being honest about your feeling. Don’t hide your feelings. Accepting your feelings can help you manage them.

Keep a healthy lifestyle.

Keep a balanced diet and follow a daily routine（惯例）. People who stay at home for a long time may easily have their routine turned upside down. Some people may stay up late at night and fail to get up during the day. Sleep is important for your personal health. Good sleep, especially deep sleep, can reduce anxiety.

Exercise regularly.

Physical exercise is also an effective way to reduce anxiety. Even a small amount（数量）of physical exercise can quickly make you feel better. And it works for people of all ages. At this time, you probably could not do outdoor exercise. But you should still do some exercise at home. If you need exercise tips, try downloading an app or find them online.

Talk to someone.

Humans are social animals. If we can’t communicate with our friends, it may lead to bad feelings. Fortunately（幸运地）, it is easy to connect with relatives and friends. Call someone or send a private message on WeChat.
