Requirements for tourist visa. I plan to visit China in June and would like to stay for 2 months.

(Visiting friends and my Chinese girlfriend ) but it is my first time applying. Am i likely to be granted , given that i provide all required documents and sufficient financial support? Also im applying from Hungary as a full time registered student but im not Hungarian nor from EU. I paid my tuition fee for the 2017 year. I would like to visit PRC again in next winter holidays. Should i apply in June for a multiple entry one or apply twice, first in june then for my next trip, which is better? I also don't think that visiting my girlfriend is enough of purpose of visit, or is it? Money isn't the issue anyway. Please give me advices on how to proceed.
