Why do some schools have swimming programs?

There are many reasons for schools to offer swimming lessons, some of which are to improve the physical fitness and health of students, while others are to fulfill the interests and needs of students. In China, more and more schools are starting to offer swimming lessons because the Chinese government is promoting a national fitness campaign, and swimming is a great sport for the public to participate in. In addition, some schools are also offering swimming lessons to meet the needs of parents who want their children to learn how to swim.
