Chun Yu Shutong's "Ancient Texts Of Reference to the Three Phases of the Contract" clearly explains what is "reference to the same". Ginseng, i.e. three, one two three three. The three phases are the astrological phase, the gua phase, and the Ding phase. Then "The fire is really well founded." ”
"Zhou YiShan Tongqi", in the past, was only called "Three Tongqi", and it is customary that different versions have different signatures:
(Han) Written by Wei Boyang
(Han) Chun Yu Shu Tong wrote
(Han) Written by Xu Jingxiu
Most of the present biographies are only signed "Wei Boyang of the Eastern Han Dynasty", and the average person does not know Chun Yu Shutong and Xu Jingxiu.
"Three Phases of the Reference Contract", alias "Supplementary Removal". The nickname is interesting. According to this line of thought, after the composition of the "Reference Contract", another paper instruction manual was written, that is, this book. This is certainly not true.
In fact, Wei Boyang's "Zhou YiShan Tongqi" is likely to be completed on the basis of books such as the Ancient Dragon and Tiger Classics and the Ancient Literature Reference Tongqi Three Similarities.
Among them, which book of "Xu Jingxiu" is not yet known.
In terms of intersection, Wei Boyang's "Zhou YiShan Tongqi" system is more ambitious, the explanation is more detailed,—— and therefore more difficult to read.
In contrast, Chun Yu Shutong's "Three Phases of ancient Chinese References to the Covenant" is not large and relatively easy to understand, so it is regarded as the secret of the "Reference Contract" and the key to opening the door.
