Wei Zi caught a cold.

In the play "Knife in the Snow", Xu Zhihu is Xu Fengnian's sister. She used to be very healthy, but in the play, she suddenly became seriously ill, and suddenly time was running out, which made people feel very strange. In fact, there are many reasons why Xu Zhihu is seriously ill. First, because Xu Zhihu caught a cold, coupled with the stimulation of the villain, Xu Zhihu was even weaker. There is also because Xu Zhihu's own life is too hard. If he lives too long, everyone around him will be affected.

First, Xu Zhihu caught a cold.

Before, Xu Zhihu's body was very ordinary. The reason why he suddenly became seriously ill was because he had a cold. In ancient times, if a person suffered from cold, it could be said that it was a serious illness and it was difficult to cure, so his health would get worse and worse. From bad to worse, Xu Zhihu himself feels that he will not live long, so his mood is becoming more and more pessimistic and negative. If the patient has been in a bad mood during the illness, it is also very unfavorable for his recovery.

Second, stimulated by villains.

Xu Zhihu had a cold before and was in poor health. Coupled with the stimulation of Yuan Tingshan, the villain in the play, Xu Zhihu was even more angry and weakened, and Shou Yuan was also greatly discounted, and eventually died. In this play, Yuan Tingshan can be regarded as a very annoying villain. In order to gain his position, he attacked and killed Xu Zhihu.

Third, the original fate of Xu Zhihu

Xu Zhihu's personal fate and life are difficult, and he is reincarnated by Zhenwu Emperor, so the relatives around Xu Zhihu generally will not have any good end, and there will be no good result. Plus Xu Zhihu's father, Xiao Xu killed too many people before, which would not have had any good results, but he died in the end, so Xiao Xu's cause and effect were all because of his children. In addition, the fate of Xu Fengnian played by Ruoyun Zhang is very strong. The more predestination Xu Fengnian accumulated, the faster his relatives and friends died, because all the good luck was transferred to Xu Fengnian.
