Can I apply for Chinese visa in HK?

Hi.. I'm a Malaysian holding Malaysian passport flying to Hong Kong for a week stay and then will be back to Malaysia for two days then flying to Guilin, PRC. I don't have enough days for Chinese entry permit application in Malaysia so can I or is it possible to apply for it while I'm in Hong Kong?
Kindly Advice me on what I shall do.. Much appreciated .
