I'm planning a trip to China next year, something which may involve four internal flights within the country.

Does any of the airlines offer a 'discover China' fare? You know where you can take a certain number of flights within the country for a set fee?

Qantas does such a scheme for Australia, but is there one for China?

Any advise would be greatly appreciated. The flight costs aren't too bad for what I'm planning, but as always if I can reduce costs then that is always good ^^
