Yin Qi is called Qi because he is the seventh living creature that Mo Kaiyan picked up after building Yin Village, which means that he ranks eighth in Yin Village. The first one is naturally Mo Kaiyan, but Mo Kaiyan can only be called Mo Kaiyan and not Yin Da. He said that this is inconsistent with his magnificent appearance. Mo Kaiyan's shamelessness is by no means the source of Yin Qi's unhappiness. What makes Yin Qi unhappy is Mo Kaiyan's laziness. In Yinzhuang, in addition to Yin Yi, Yin Sa, Yin Wu, and Yin Ren, there is also a parrot named Yin Er and a black cat named Yin Si. This shows that Mo Kaiyan is really lazy. He just named them in the order they were picked up without putting any thought into this symbol that may affect people's lives.
I really like the pink color of Daguo and Sixi.
