What I know about this long term visa is a permanent resident visa given only to expat millionaires or the very,very rich expats,who invested a lot of their money in china.Before they will give you the visa,they are going to screen your financial portfolio,&if you are qualified accdg.to their own standard,that's the only time they will give you a permanent residence.But I repeat,we are talking about "big time" money here,not just "money".I hope this will give you an idea.Why not try,who knows you will be accepted.
