Why is there so much emphasis on "double" in "The Patriarch of the Demonic Way", the Lan family's double jade, and the Yunmeng's double jade?

I feel that "The Patriarch of the Demonic Way" seems to be very fond of "double". The Lan family's double jade, Yunmeng's double jade, and even the rabbit are all double!

Lan's Double Jade

Lan's Double Jade refers to the Lan brothers Lan Xichen and Lan Wangji. Although they are several years apart, they look very much alike. Lan Xichen is gentle and gentle, while Lan Wangji is cold and cold. Both of them are elegant, upright and well-known young men. Lan Xichen is called Lord Zewu, and Lan Wangji is called Lord Hanguang. Among the young masters from aristocratic families, these two are at the forefront. Suddenly I want to know what it would be like to have a brother who looks like me? Anyone who knows can tell me?

Yunmeng Shuangjie

The Lan family has a double jade, and Yunmeng has a double jade, Wei Wuxian and Jiang Cheng. Wei Wuxian is the eldest disciple of the Jiang family, and Jiang Cheng is the son of the head of the family, Jiang Fengmian. The two grew up together. Wei Wuxian is more lively and out-of-the-box, while Jiang Cheng is more steady, as long as he is not in front of Wei Wuxian. Yunmeng Shuangjie is also an extremely outstanding young man from aristocratic family, rich and handsome. Jiang Cheng is dressed in "gay purple" and has a very elegant temperament, but the adult Jiang Cheng is more serious and can be said to be cold and stern.

The Nie brothers

The Nie family in Qinghe are also two brothers. The elder brother Nie Mingjue is powerful and has superb swordsmanship. As the head of the family, the Nie family is very prosperous. The younger brother Nie Huaisang is relatively timid, mediocre and not good at martial arts. However, it would be wrong to think that Nie Huaisang is an incompetent person. Is Nie called Director for nothing? He did lead a good show. In order to avenge his brother, he induced Mo Xuanyu to sacrifice his body. The Yiling ancestor returned and passed the ghost hand Step by step, Jin Guangyao is forced to a dead end. Both Nie brothers are ruthless characters.

Two Rabbits

Even the rabbits in "The Patriarch of the Demonic Way" are in pairs. As a single fairy, it means that he has received 10,000 points of damage. Wei Wuxian gave Lan Wangji two rabbits. Are they considered love rabbits? Later, Lan Wangji kept raising it. During the thirteen years of Wenling, the second brother Lan was probably in a daze for the rabbit. Thinking about the way Brother Lan holds the rabbit, I feel so cute inexplicably.

Double Taoist CP

There is also a pair, that is, the twin Taoist CP, Mingyue Qingfeng Xiao Xingchen, Aoxue Lingshuang Song Zichen. The two Taoist priests are actually quite sadistic. They share the same goals and are close friends. Xue Yang slaughtered Song Zichen's Taoist temple and destroyed his eyes because of Xiao Xingchen. Xiao Xingchen violated his master's oath and begged Baoshan Sanren to save Song Zichen and goug out his own eyes to compensate him. Later, Song Zichen went to look for Xiao Xingchen. Until his death, Xiao Xingchen could not see Song Zichen again because he couldn't see him and killed Song Zichen by mistake. Song Zichen also chose not to say anything, fearing that Xiao Xingchen wouldn't be able to bear it.

The above is purely my personal opinion.
