hongkong transit visa

Your passport, application form (ID1003A), a recent photo(48mm×33mm), a copy of passport information page, a proof of travel itineary and other valid documents for your next destination. If your application is handled by Chinese embassy in your country, you will get it on the fourth day after your submission. If it was sent to HK Immigration Department, you will wait for a month.

thank you for details.actually my first entry china one 30 days .after that I need to participate another exhibition in beijing .for that I need to re entry China.then I thought to apply for Hk Transit visa.my question is transit one enough for my reason.is it...!pls let me know

But once you get a HK transit visa, you still need one more entry if you want to go back to mainland PRC. It is ok if you have double entry.
