The two had been together for 6 years though it appears Jun, who twice lost in world title bouts to Nehomar Cermeno last year, has left the relationship due to financial issues and a lack of trust with the manager who had guided his career to two title fights. Gang on the other hand is said to have been annoyed about the way Jun has left him and the accusations made by the fighter, as well as a lack of professionality from Jun.
Both have spoken about the falling out, and it does seem that both may have some fair points, but the reality is that one of the most fruitful and notable relationships in Chinese boxing has broken down.
By it's self the story looks like another in a long line of fall outs between fighter and promoter, but digging deeper it could well be a telling damnation of the Chinese boxing scene, which has shown some promise at times, but has been stumbling in 2017. Not only has the most powerful Chinese promoter lost his most notable fighter but the biggest name in Chinese boxing, Zou Shiming, has struggled to get funding for his first world title bout. The hope of making China into another boxing country is faltering and the downturn in the gambling sector in Macau certainly hasn't helped things.
It's unclear if Jun is set to sign with a new promoter, walk away from boxing of become self promoted, but it's clear that this fall out is one of the most significant in Chinese boxing. It's potentially lead to a lack of trust between fighters and Gang, and if Jun's words ring true other fighters may also be ready to speak out about him, whilst Jun may potentially have shown a sign of petulance, and could see promoters turn off him going forward.
