After travelling for so long I have never consider the cheaper accomodation called Hostel. Why didn't I think of that. Cos I feel that Hostel has provided me with all that I need + I get to meet people from other country, though I dunno how to interact well. It'll be a plus if I get to follow them and help them in China. So I'm planning for a solo Beijing trip very soon.
