good day sir, i come to china with a 90 days visa, and recently just got approved of another 90 days, 1 entry visa extension, valid until October5, 2010. I plan to go back to Philippines after 2 weeks for 10 days, then come back to China. Do i need to apply for a new visa? or the visa extension can be used as my entry visa? am not so familiar about it..... thank you very much.....
