Judging from all Mr. Li Geng's works, the content is written around Heze. The characters in the works, such as broadsword generals Zhao and He Siyuan, are all writing about Heze people and promoting Heze culture. In his own words, "trying to dig up these hidden or forgotten things can be regarded as doing a good thing for his hometown", and it is indeed the case. Dwelling in a college in a small town in Shandong, I set a desk in front of it, and in the vast wilderness, I closed my "hometown dialect permeated with bone marrow". I only listened quietly to the ephemera scattered in The Book of Songs Cao Feng, and listened to the pulse and heartbeat of people and customs in western Shandong.

Reading Li Geng is actually more like reading a book, a thick encyclopedia.
