From what I understand (not having actually married a Chinese woman), yes, there are some benefits in terms of visas, etc., but I also understand from knowing a number of expats who married Chinese women, there can also be "hell to pay" when seeking divorce, etc. in Chinese courts. The Chinese spouse has the "upper hand" by a long shot. Chinese courts are not sympathetic to expats.

Best to marry for true love (in my opinion). Find other means to obtain visas and such.
