In China, even though many parents send their children to learn swimming, the teenage drowning mortality rate is still very high. Therefore, I designed a new service system based on the Water Cube Swimming Club and adjusted the service area. Children can choose the appropriate courses according to their own physical conditions, and then carry out intelligent swimming training after in-depth understanding of the importance of swimming. Through digital means to track and control each student's swimming training, so that the coach, students and parents can cooperate with each other to improve the training effect of children.
