Are Zhouyi, Dongyue and Ziyue collectively called Ziyue?

Twelve ugly children, namely Yin Mao,,, and, together with ten days' work, form sixty cycles, which are called sixty flowers. It is a tool to record China's antiquity. This time is divided by solar terms, that is, beginning of spring is silver moon, Uzuki is a fright, Qingming is Chen Yue, snow is Confucius, and slight cold is ugly. Whether it is Hainan or Northeast China, this is the law.

The gentleman you are looking for is wrong in any case. You can ask him if he invented the calendar himself. I am a fan of Zhouyi, and there is such a person in Zhouyi circle. I have nothing to say but tell him to mind your own business.
