说到中国文化,不能不提到长城。从公元前7世纪到公元16世纪,在大约2 200年的时间里,先后有19个朝代修建过长城,所修的长城长达10万千米以上。主要的长城修建工程是在秦代、汉代和明代完成的。现今存有遗迹的主要是明长城,从东边入海口的山海关(Shanhai Pass)开始,一直到沙漠深处的嘉峪关(Jiayu Pass),全长约6 700千米。长城是世界历史上最伟大的工程之一,其建造时间之长、参与人数之多、工程难度之大,在世界上无出其右。
When it comes to Chinese culture, the Great Wall is the one that will be definitely referred to. Through about 2 200 years from the 7th century BC to the 16th century AD, the Great Wall was built in 19 dynasties and reached a total length of more than 100 000 kilometers. The major construction was carried out in the Qin, Han and Ming Dynasties. The Great Wall we visit nowadays is mainly the Great Wall of the Ming Dynasty, stretching about 6 700 kilometers from Shanhai Pass at the eastern river mouth to Jiayu Pass in the depths of desert. The Great Wall is one of the greatest projects in the history of the world for its unparalleled span of construction, amount of labor and difficulty.
This is the aim of traditional Chinese painters: not only to describe the outer appearance of a subject but also to capture its inner essence—its energy, life force and spirit. They achieve this with the most economical means: brushes and ink. In order to reach this goal, they tend to reject the use of color. Like photographers who prefer to work in black and white, traditional Chinese artists regard color as the distraction. They also reject the use of light and shadow, which have changeable qualities. Instead, they rely on the line—the indelible mark of the brush and the ink. The reason why traditional Chinese painters can master this skill likely lies in their previous practice of calligraphy.
Today, online education is popular with parents and children because of its quickness, convenience and diverse content. Online education is in full swing, and the most popular form of educational products now is live streaming. Nowadays, with the development of online education, the class has come a long way from being a one-way activity in which the teacher gives the talk while the students are listening, which is cold and rigid. Various diversified learning methods make the classroom active and are no less effective than face-to-face communication in the offline classroom. Teachers can invite students to interactive classroom activities in a timely manner according to the teaching rhythm and classroom situation, so as to maximize students' enthusiasm for the class and create an active classroom atmosphere.
In China, education is seen as a high priority for families, and many regard extracurricular courses as a way to give children an edge.

Online programming courses and brain training courses are becoming more and more popular in the online education market. The second-child policy and emerging technologies, including artificial intelligence and live streaming, have contributed to the country's booming online education market.
It is reported that China's sharing economy is expected to maintain a rapid annual growth rate of more than 30% in the next five years. The rapid development of China's sharing economy reveals the tremendous vitality and potential of the Chinese economy, but it is facing many challenges. With the rapid development of the sharing economy in the fields of transportation tools, accommodation, catering, etc., new problems such as personal information leakage, waste of resources and unfair competition have emerged. The reasons behind the problems with the sharing economy are complex and diverse, but a common problem is that the main responsibility of the sharing platform has not been properly shouldered. A government notice has pointed out that the government will strengthen supervision over the collection, use, sharing, transfer and public disclosure of personal information on sharing platforms.
