Now winter season not really good time to go china, yes though good
3/4 star hotel is now quite cheap due to down season but transport
in china is never cheap be it domestic flight bus or train.
Some more if you shop during winter season all they have on sale is
winter clothing, winter clothing is useless in singapore
climate.
best time to go is Oct just cool temp and not hot.
