The ice show is a commercial performance with economic income. Except for athletes in the system like our country, most foreign athletes have to pay their own training expenses, including clothing production, so they need to make money in Shang Yan in the off-season. Generally, China athletes don't participate in Shang Yan because the state pays for sports, but in recent years, they have gradually started to get in touch with international commercial performances. On the one hand, it is the general trend of commercialization of our ice and snow projects, on the other hand, it can also exercise athletes and subsidize sports funds.
