I love this website, very informative!
I would like to ask about visa application and hope somebody can help me on this. I'm a Malaysian who will be travelling to Shenzhen next year. I know that I have to apply for visa to enter China. The thing is I would like to visit Hong Kong for couple of days and therefore am wondering do I need visa in China to enter HK? And from HK do I need to apply for visa to enter China(Shenzhen) again as my flight home will be from Shenzhen?

Hope anybody will help me on this...

I thank you in advance.
