Most players are not professional players, and they are driven by pure pleasure and genuine interest to the sport.
Men's hockey is an exception in this year's game.
My mother use to be an athlete playing in the provincial level. There is one time I watch with her together and ironically found she is not cheering on the side of her own country and she commented on the reason this: These Athletes' training is full time all day. It is not fair for the other countries athletes.
True, Fairness is the true spirit of playing sport. Nowadays people in PRC seems not consider this anymore.
