As for the authors of Shan Hai Jing, some people think that they are Dayu and Boyi. According to legend, the Xia Dynasty was established after Dayu controlled Kyushu. When he established the Xia Dynasty, he wanted to record his daily achievements and understand the mountains and rivers of the land he ruled, so he sent a scientific research team to make a special textual research and record on Kyushu under his rule, so as to show that the whole world was not the land of the king.
The head of this expedition is Boyi, who did not write the Classic of Mountains and Seas completely, but painted the geographical features of Kyushu into a huge picture scroll, which was later engraved on the Jiuding of Dayu. However, in the Qin Dynasty, although Jiuding had been lost, the map of Shan Hai Jing recorded on Jiuding was preserved and handed down, which was also the most original version of Shan Hai Jing, so many people regarded Boyi as the author of Shan Hai Jing.
The Classic of Mountains and Seas that we are seeing now was compiled by Liu Xiang in Han Dynasty, so some people are speculating that maybe the Classic of Mountains and Seas is just a book written by Liu Xiang in the name of the ancients. In addition, Guo Pu once made an addendum to The Classic of Mountains and Seas, so Guo Pu in the Jin Dynasty may also be the author of The Classic of Mountains and Seas, because the ancients also deleted it into their own works on the grounds of compiling ancient books. Moreover, this "national genealogy" does add three parts: domestic classics, overseas classics and wild classics on the basis of the original five Tibetan classics. The Classic of Mountains and Seas, which we are seeing now, is supplemented by these three articles. So when Shan Hai Jing is published, some people will call the author of Shan Hai Jing Guo Pu.
