When Wei was afraid of dogs, why did he subconsciously call the teacher elder sister instead of Lan Zhan?

In The Untamed, Jiang Cheng threatened Wei Wuzhen with a dog. In extreme fear, he unconsciously shouted "Sister". Many viewers said they didn't understand this, because Wei Wuzhen had just come down from the mountain when he met the immortal. He was shouting blue camp. When he arrived at the hotel, he was frightened by the dog. Why did he call his sister? After all, my sister has been dead 16 years. How can this help Weiwei catch a dog?

When Wei Wuxian and Blue Forgetting Machine meet again, their feelings are different. Although there is still no wave on Lan Forgot's face, his heart is already surging. Even Wei Wuzhen didn't know that Lan Zhan began to become his star and hope. The person who once helped Wei Wuzhen stop the dog has always been a sister, but since the appearance of Lan Zhan, everything has changed imperceptibly. People who used to stop dogs were unconsciously replaced by blue wars, and even Wei Wuzhen didn't notice it.

After Wei Wuxian shouted "Sister" in despair, after Wei Wuzhen rushed out of "Sister", Jiang Cheng spit out "Sixteen years, Lan forgot to protect you". You can guess that Wei Wu's name is "Blue War" from Jiangcheng's sentence "Blue forgets the machine, but still won't forget to protect you", but he is too scared to know how to shout. But hearing Jiang Cheng's words only shows that I am actually calling "Lan Zhan".

The relationship between Lan Zhan and Wei Ying in the play is also shown as "brotherly relationship". As many viewers are worried, because "Chen Qingling" is a very original line and plot, although the audience is very cool, it is also accompanied by "ready-made" risks. Therefore, in order to avoid suspicion, the Drama Troupe directly changed "Blue War" to "Sister", but if we look closely at Wei Wu, we will find that his name is "Blue War", but this passage is silent. After processing, the later dubbing became a "sister".
