Where can I find good silk in Guangzhou. Also, are the jewelry shops there as plentiful as Hongkong? I am talking about real jewelry.

Also, if I have a single entry to China, from Manila will I be able to go Hongkong and back to China again with this single entry?

Does the Chinese government recognizes Hongkong part of China that my visiting there from Guangzhou is like still being in China?
Thanks
