I did it last year in Beijing. You can only do it after 11/9. Make sure you do it no later than 13/9 if you want to do it in beijing, because later than that the immigration may ask you to do a body check. Just download the form and pay the money, you should get it done within a week. Good luck :)作者: sunnysun00000 时间: 2011-8-9 09:05:29
