I need to go to Hong Kong on 21 oct to 27 oct but my passport exp date is on 11 april 2015

Should I worry?, I heard that I cant pass the immigration if my passport expiration date is less than 6 months. But after read all the information above I just not sure about this. by the way I am from India and have to go to Hong Kong with my family for a 6 day hoilday. So what about me?
