You're kidding right? He is far from young in football standards. They guy is 31 years old! He's very lucky he's getting paid by a club with those wages.
He have a huge fanbase in china, that could be the only reason that the chinese club choose him. They are using his popularity to attract football fans to support their local league. If there is no huge fanbase for him in china then there is no way that they will be signing him, he is more than just lucky
That is business more not football sorry but that's how it is now everywhere they want more money just money no re sport
