My husband and I are planning a world trip and China features towards the middle of the journey. If we get a double entry visa from Brisbane before we leave do we have six months to arrive in China? I am a bit confused - in some places it says six months but in other places it suggests you still need to arrive within three months? Also, we want to spend about 45 days in rural China - is it possible to apply for a 60 day visa up front or do we have to get it extended while in China? We're not planning to go to the big cities so I am worried about how to extend the visa. Thanks!
