Falling on March 20 this year, Spring Equinox, also called Chunfen in Chinese, is the fourth of the Twenty-four Solar Terms. It marks the same length（长度）of the day and night.

Have you ever wondered about the origin（起源）of this special solar term? It is said that a long time ago, as there was not enough sunlight, it was almost impossible for people to grow crops. One day, Emperor Yandi decided to fly to Penglai Island on a five-colored bird to search for the sun so that his people could enjoy a better harvest. After a dangerous journey, he brought the sun back and hung it in the sky. From then on, there were plenty of crops on Earth and people lived happily and peacefully. This day is called Chunfen.

Today, people in different places have different traditions to celebrate Chunfen. Chunfen is the best time to fly kites. The wind for kite flying can’t be too strong or too gentle. The gentle wind on the day of Chunfen perfectly satisfies those needs, so it is easier for kites to go up. It is usually a wonderful time for people, both old and young, to go to the open spaces to fly kites. It is believed that flying kites on Chunfen can drive away bad luck and bring back good luck.

Chunfen also means hope and growing up, just like the plants. Since ancient times, people ate food based on the changes of seasons. In southern China’s Fujian and Guangdong provinces, people living in villages dig wild vegetables and cook them in soup to clean their stomachs. The meals are also thought as a way to wish for a healthy and strong body. During Chunfen, wheat grows and flowers come out. Leek（韭菜）is delicious and fresh. It’s the best time to cook food with it, although cooking styles are quite different between northern and southern China.

When Chunfen comes, remember to have fresh vegetables on your table. Also, don’t say no if you are invited to take part in different activities to enjoy the good weather.

【推荐2】On June 18, 2018, a number of small driverless delivery robots were taken to the streets for the first time from the Shangdi delivery station in Beijing’s Haidian District to improve delivery service and reduce the cost.

The red and white delivery robots stood in shining line around the Shangdi distribution centre, one of JD’s main delivery stations. The driverless robots usually deliver 30 boxes of products at a time, reaching 15 kilometres per hour. It can carry up to 300 kilograms of goods.

“The deliveries covered most of the living areas near the distribution station,” said Yang Jing, general manager at JD’s AI Research Department.

“Information of the machines was already on record connected with the local transport department of Beijing before they were taken to the road,” said Yang.

The robots can avoid barriers and people, stop or go according to the traffic lights and make their way to the delivery sites all by themselves.

“We are using delivery robots to reduce the human costs of traditional delivery service,” said Yang. JD has already used delivery machines in several closed areas, such as colleges and parks of companies. JD plans to put more than 100 delivery robots in use in more than 20 Chinese and foreign cities, such as Shanghai, Tianjin and Xi’an in China and Bangkok in Thailand.

【推荐3】Did you walk into the cinema on National Day and watch the movie Changjin Lake（长津湖）? It’s about how the new China helped North Korea to push back the American soldiers（士兵）. It is not only the movie itself that makes people touch, but the heroes of the war who fought for our country and the people.

Let’s take a close look at the real-life history behind the movie. Changjin Lake is in North Korea. The Battle（战役）of Lake Changjin was in a very cold winter with temperatures（气温）of around -40°C. In the 1950s, our Chinese soldiers had to face life-and-death problems when they got on the train to enter the DPRK. A US enemy plane bombed（轰炸）the trains, and the soldiers had to quickly moved into the mountains and forests to hide. I still deeply remember a picture in the movie. In order not to expose the target（暴露目标）, they stayed in the ice and snow without any moving. Although the follow-up troops（后续部队）killed the enemy and won the battle, unluckily 125 soldiers were frozen（冻）to death. This is a movie about war and people. Many can’t help crying after watching this movie, because our Chinese soldiers used their lives to guard（保卫）the country and the people.

It is the loveliest persons who guarded China’s great rivers and mountains. However, many of them never have the chance to see the beautiful mountains and rivers again. The movie Changjin Lake wants to tell as today’s young people：though we live in an age without war, we should never forget the true heroes in the history and we need to pass on their great spirit!
