Abstract: The frequent lack-of-good-faith instances among Chinese sports professionals have attracted increasingly wider concern in recent years. A thorough investigation into these instances reveals that the sports managerial personnel, the coaches and the family members of an athlete have all played a part in such disgraceful incidents. A cause analysis is made and the harm the lack of good faith does to the sports cause is elaborated and concludes that such occurrences will eventually pose severe threat to the Chinese sports image as a whole.
