I would give 0 if possible. Our flight got cancelled while we were back waiting at the gate for the second time for boarding (after 10 hours in total and 3 hours waiting in the plane). During the waiting time we did not receive any food or drinks, no accommodation or taxi, resulting in additional costs. I spoke to their Chinese customer support many times and was promised a response via phone but have never received a phone call back. It is now one year later and we still have not received anything back from the airline - do not book with them!!!
