Why are the seven signs of Yun Qi called the collection of traces?

Yun Qi's Seven Signs is called Jingji because Yun Qi's Seven Signs is a large Taoist book compiled by Zhang Junfang in northern Song Zhenzong, with a total of 122 volumes. "Yun Fu" is the Taoist name for bookcases, and "Qi Fu" is the combination of "three holes" and "four assistants". The title of "Cloud Seven Chapters" is to sum up the meanings of all kinds of ancient books in the Taoist teaching frame, so the world calls it "Small Road Collection".

Taoism calls the collection of books "Yun Fu" and the volumes are "Three Caves and Four Auxiliary Books". Therefore, in the preface of the book, Zhang Junfang said, "Yunfu has a strange shadow, and a little treasure accumulates all the philosophers' Austria", so it was named Yunfu Qian Qi. Some people say that the purpose of compiling this book is to "repay the kindness of Zhenzong, prepare for your majesty's visit the next night, and act as a proofreader in the literature museum, with less mystery."

Although Zhang Junfang called this book "English for Seven Books", it only refers to the English for seven books in his personal mind. Its content is the scripture that can best reflect the Shangqing school in the seven books of the Heavenly Palace in the Great Song Dynasty. However, Zhang Junfang thinks that these Qing School Classics are the English of the seven books in the Temple of Heaven in the Great Song Dynasty.

The style of "Seven Signs of the Cloud" imitates "The Supreme Secret" and is purely headed by Taoist thought. It is like a volume of the Ministry of Morality, picking out the words from The Return of the Old Man, Han Feizi, Huai Nanzi, Preface to the Sacred Discipline of the Mixed Yuan Dynasty and Preface to the Tao Te Ching of the Emperor Kaiyuan of Tang Dynasty, so as to summarize Laozi's moral outlook, that is, the purpose of establishing Tao.
