In terms of entry-level reading materials, many works published by domestic fans can be bought in the domestic market or shopping websites, as well as other peripheral game series represented by Shinkawa, subtitle versions of Japanese history columns such as historical moments and river dramas, Chinese versions of historical novels represented by Yamaoka Sōhachi, Yoshikawa Eiji and Ryotaro Shiba, and Baidu Encyclopedia entries. The above channels can meet the needs of 90% ordinary fans, and a basic understanding of the outline of the Warring States period should be enough. But the disadvantage of these materials is that they gather a large number of readers and are interesting to some extent. Some of them are just general remarks or quotations from a military discipline, especially for novels and river dramas, which are more likely to be subjective changes and supplements by the author, but in fact they are not facts, just that beginners are not easy to distinguish, and they can only get a deeper understanding with the deepening of learning.

As for primary reading materials, some domestic monographs on Japanese history cover the Warring States Period of Japan, such as Nankai Edition, Feng Wei's Japanese History, Japanese Middle History, Tong Yunyang's Socio-economic History of Japan in the 6th Century 15, 16, Zuo Xuede's Research on Land Issues in Japan's Historical Transition, and Peter Ann Nulsen's Famous Names of Japan in the Middle Ages. They are all related books in Chinese, and the articles written by some senior domestic fans included in the special issue of finger writing can meet the entry needs of some friends who want to know more about it.
