Whether the ship reaches the predetermined position or the route is correct, it is necessary to compare the mountain shape. Whether the ' mountain shape ' on the water potential map is accurate or approximate determines the success or failure of navigation. Chen Lunjiong (2013) pointed out, the drawing of mountain shape is very important. Professor Yan Genqi (2019) pointed out that ' Wangshan ' refers to the obvious markers such as mountains and forests on the coast, such as Tongguling in Hainan Province, which is named after the bronze drum excavated by General Ma Yuan during the reign of Emperor Wu of the Han Dynasty. It is an important ' Wangshan ' that ships from Guangzhou and other places enter the sea area east of the Qiongzhou Strait and sail southward. In Zheng Changmei's copy of "Liushui Genglubu", there are many descriptions of the mountains. For example, from Lingao in Hainan to Bingmajiao, on the way to see the three major mountains, Songlinling, Bao 'anling and Bingmaling, From Lingaojiao to Diaoloujiao, it is necessary to turn the needle many times to change the direction, and there are many reefs. It is difficult for people who are not familiar with it to pass through. That is to say, the voyage is very complex, reefs, sand, all, the text can not be all loaded, must be very familiar with its terrain. （ This is page 5 of Zheng Changmei 's copy of " Liushui Genglubu ", From Lingaojiao to Diaoloujiao. ） " ( )D
