There are too many of these threads popping up, so I'm just going to touch over the options and close it, because I think only you should make this decision as a consumer of FM2010.
Staying would be good in the sense that you have the huge challenge of leading an Asian team to any success outside their domestic league - a tricky feat to accomplish, but a fun, rewarding one - I can imagine.
If this isn't what you want, and you want to manage at the highest level (Which I find unlikely, considering you started with an obscure team) then move to Liverpool.
Alternatively, you can save the game seperately, move to Liverpool, then if you aren't enjoying it, load your old save and continue with 'South China'.
