Winter is a serious young man who thrives under socialism. As for Xia Tian, you can't say that she is not serious. She is just a little stupid and stupid and failed to take advantage of the opportunity of excellence. Anyway, she said that she can't be blamed for all this. As for who to blame, it should be all the fault of Dong Dong, a pervert who is too serious. . . . So just like water and fire, day and night, the rotation directions of the southern and northern hemispheres are the same, what will happen in winter and summer?
