Why don't you sell Da Liu Ren's books?

Because the original work has been lost, and few people know it later.

Taiyi, Liu Ren and Qimendun, collectively known as the study of emperors, have lost their original works in the historical and cultural trend. At present, what can be seen in the market is not the real Tai Yi and Da Liu people. Even if there are, the real knowledge is in the hands of those who have passed down. Because time is too long, few people know it, and those that can be preserved have been broken for hundreds of years in modern times.

Da, Taibai in the Tang Dynasty was recorded as a nine-day Xuan Nv style, and books such as Warring States Policy recorded a few big words. Da Liu Ren originated very early. Inferred from the historical time, Zhouyi was created by Zhou Dynasty after Shang Dynasty, and Great Liu Ren was classified as an ancient system, which was earlier than Zhouyi. There are three kinds of records: Yi, Lian, Gui Zang Yi and Zhouyi. At present, scholars who study historical Yi-ology generally recognize the classification of the three changes: Lianshan Yi in Xia Dynasty, Gui Zang Yi in Shang Dynasty and Zhouyi in Zhou Dynasty. The earliest cases of six people can be found in Wu Yue Chun Qiu and Yue Jue Shu.
