To say that Jia Ling's boyfriend Qiao Shan and best friend Li Xueqin rolled the sheets and had a dark knot, although this thing is not done in a good way, it is not incomprehensible. In the film, Jia Ling plays the girl Le Ying, she is not only a problem of huge fat, the key is that she stays at home every day, does not earn money, has no hobbies, and is in a semi-autistic state, from appearance to personality to conversation, none of them are likeable. For his girlfriend who is getting worse and worse, Qiao Shan has a change of heart, which is too normal. 
However, we recommend ending a relationship first and then starting a new one. Although Li Xueqin is quite rough and quite big, compared to Jia Ling, she is a normal person no matter what, and she can be coquettish and knock on the blackboard - coquettish! In the film, Qiao Shan is not a great rich and handsome, he is just an ordinary man, there is a normal woman who is coquettish at him, occasionally charming between his eyebrows, and his coquettish little fist beats people up quite energetically. So ten out of ten men will choose this normal woman who knows how to be coquettish, instead of a silent and eccentric big fat girl who lies flat every day. 
Judging from the last appearance of Qiao Shan and Li Xueqin in the film, they are married and have children, and their relationship is quite good, Li Xueqin is still coquettish, and she is the kind of "oops, dead ghost......The daughter-in-law of the Northeast. Of course, we still recommend ending a relationship first, and then starting a new relationship.
