Baduanjin，a kind of exercise known as a sport among the old people，has become popular among the young people in China recently.
    A video produced by the General Administration of Sport of China（中国体育总局） to teach the public to do the exercise has been watched about 10 million times on Bilibili，a video platform in China.Most of the viewers are from college students and the young people.
    Compared with other sports such as the ball games and swimming，Baduanjin needs no equipment（器械） and needs very little space.In fact，it's good for young people，especially students，as they often get lower back and pain in the neck caused by hours sitting in front of the desks.
    "I have been doing Baduanjin for about four months.It makes me sleep well and get stronger.I should thank Baduanjin since it gives me a much healthier lifestyle，" a young man wrote below the video.
    Starting in the Song dynasty（宋朝），Baduanjin has a history of more than 800 years.It has eight movements.
    But not all people are suitable（合适的） for practicing Baduanjin.Liu Xiaodan at Shanghai University said that people should always put safety first when doing Baduanjin，and people who are weak or easily fall should not take up this exercise.
