Hahahahaha ... let's just say that even though Chinese are great as "team player", they don't do well in large teams .... e.g. they do OK in basketball, right?
It's like playing Maj Jong ... my mother loves the game, it helps to keep her mind running and engaged, but, for many reasons, they play different rules at either of the pensioner gatherings that she often went to, so being that most of the people have an "unknown" future (hell, they are in their 70 or 80, and some people do "disappear"), she decided to adopt their rules instead of teaching them what might be "right", or, at least a better way to play ...
If you intend to live here for another decade or so, and continue playing soccer (football) with more or less the same group of people, do continue the good work of teaching them the proper soccer rules, otherwise, just have fun at it and dont get frustrated over it, because after all, you wanted to have fun to play it, right?
