The story is about people from all over mainland China, living in "Happy Youth hostels" in which all kinds of things happen. Here guests each have their own purpose, some come for love, some for decompression, some come to get rich, some come to get closer to their partners, some come to fulfill social obligations. Each episode tackles a different situation in a completely different genre (ie. Ep 1 is a comedy, but Ep. 4 is Sci-Fi) .
