i got chinese visa( L ) valid from May 5,2011 - June 5, 2011..

i want to ask if ever i didnt go china during that date, and i want to come to china next time.. What procedure do i need to do in order to have a chinese visa again?

i was on hold in Philippine imigration because of lack of requirements from my fiance. We planned to get married in China. He's a Chinese citizen, only have 10days vacation in China because he is a permanent resident in singapore and currently working there. Once we provide the requirement in imigration, he probably finished his vacation there, and i dont have any reason to go China anymore if he's not there.
pls help, thank u..
