Cao Yunding likes playing football since he was a child. There was no room at that time, so he played in the alley with his friends. His father is a football fan. Seeing that his son loves football so much, he has the idea of sending his son to play football. At the age of 7, he entered a famous football school in Shanghai (No.2 Primary School of Pingli Road, Putuo District). In 2000, he set foot on Chongming Island and became a disciple of Xu Genbao. At Chongming Island Football Training Base, his life is like a boarding high school student. He gets up at 7: 0015 every morning, has breakfast at 8: 00 and turns off the lights at 9: 30 in the evening. Besides training, PSP and reading novels became his only pastimes. There is almost no place to consume nearby, and the supermarket is 30 kilometers away. After living like this for seven years, I am completely used to the lonely days. "I was a little sad at first, and I was particularly homesick at night." "There is no money to buy a laptop now, and PSP is the most played by everyone in the base." Every night at 7 o'clock, Cao Yunding will go to the TV hall of the dormitory to watch sports news. After that, he got together with other children, some watched their own DVDs, and some played games together. At 9 o'clock, Captain Wang Jiayu will put away his cell phone and PSP one by one. "When I go home on weekends, I go online or go out with friends. There are not many people we contact, but the people in the team go out to play together. "

In 2004, Xu Genbao began to let players practice sign language. "The coach will sign one on the blackboard first, then let everyone design it themselves, and finally show it to the coach." Cao Yunding and his teammates set their sights on becoming famous in the future.

Cao Yunding has a dream of going abroad. "My greatest hope, of course, is to play abroad. As for the club, I hope it is a team in La Liga, because I think I am a skilled player. " The national team should be every player's dream. At this point, Cao Yunding has his own understanding. "It's a bit complicated not to get into the national team, because it's not something I can get into if I want to."
