Thank you @starflyergold and @TheShis. I'm planning to have winter holiday in Beijing dan Harbin but I'm not sure if my leave would be approved since I've already spent them all till this July.

By the way, TheShis I've already checked your photos and review in tripadvisor. Wow, it's sooo magnifique !!! So tempting anyway. I hope that I could go to Beijing this winter. Thanks for posting your photos in Tripadvisor anyway.
