Before contests, the national team always held training camps to prepare.
In the beginning of these training camps, many athletes and coaches would be recruited. The training camp had several phases. As training moved on, after each phase was completed, a large number of people would be eliminated. Only a few people would remain on the team to represent the national team for the Asian Games. Each event had one to three participants.
Dai Li was not the only coach being called up from the Hanbei Provincial Athletics Team. Besides Dai Li, there was another coach. Meanwhile, two athletes from the team were also called up to attend the training camp.
