Hong Kong visa for somebody

I am a Bangladeshi national who has a residence permit for China, I live in Guangzhou, can my friend who is visiting Hong Kong apply for a permit on my behalf? I need to exit and reenter China as my residence permit is expiring in a few days time and the closest city for me to do this is Hong Kong and I wanted to get my friend to get a tourist type to Hong Kong for me and then come back with my passport so I can go to Hong Kong and then apply for a China one in Hong Kong. The embassy for Hong Kong is in Beijing otherwise I would apply myself for the the permit to HK.
