Volume XXIII Issue II Version I 7 ( ) Global Journal of Human Social Science - Year 2023 D © 2023 Global Journals The Newly Discovered Graphic-Text Combined Study of ' Liushui Genglubu ' in the South China Sea c) Drawing of water potential In the mountain water potential map, the water potential mainly refers to the marking of the marine hydrological conditions and geological conditions around a port and ' mountain ' in the map, as well as some navigational south, the most important of which is the depth of sea water and the geological conditions of the ocean, such as sand and reef. In Zheng Changmei's copy of the " Liushui Genglubu, " there are many pictures that record the water potential, and there are some specific terms, such as hidden row, clear row, reef cornerstone, coarse sand, fine sand, sand land, sand mud land, mud land, Pingyang water land, Zhengli, Dashui... Bracket, water depth... A foot, offshore... Pitching, dark water all the way, etc. As shown in the figure on page 25 of this book, the map of mountain shape and water potential in Guangdong is drawn, including the mark of Naozhou lighthouse, ' here is scattered sand ', ' shallow water here ', ' Pingyang water ', ' water dry ', ' shallow water ', Zhengli and other geological conditions, water potential drawing. (This is page 25 of Zheng Changmei 's copy of " Liushui Genglubu ", The map shows the ports, routes, voyages, mountain shapes and water potential along the route from Guangdong to the East China Sea. ） d) The integrity of the diagram Throughout Zheng Changmei's 24 maps of ' Liushui Genglubu ', it can be seen that although the 24 maps are divided into different page numbers, they are linked together to form a complete map with very obvious holistic characteristics. Among them, from page 1 to page 21, is the Hainan Island map. Starting from Haikou, Hainan Province, involving Haikou, Chengmai, Lingao, Danzhou, Changjiang, Dongfang, Ledong, Sanya, Lingshui, Wanning, Qionghai, Wenchang and other coastal cities and counties on the west and east coasts of Hainan Province, through Shashangjiao - Hongshajiao - Tianweijiao - Beinancun - Dongshuigang - Huafanggang - Yubaojiao - Magang - Hongpaigang - Beipugang - Linggaoshangjiao - Linggaoxiajiao - Tiaoloujiao - Tianchenggang - Long 'anjiao - Xinyinggang - Houshuigang - Huangshajiao - Bingmajiao - Emangang - Nantangang - Shenjianjiao - Ganchonggang - Baimajing ( Yangpu ) - Guanyinjiao - Haitougang - Haiweigang - Shatang - Shatang - Shatang - Shatang - Shatang Bay - Changhuajiao - Changhuagang - Changtianshagang - Yishagang - Lingshuijiao - Li 'an Port - Shuikou Port - Sugarcane Island - Xiaohuajiao - Dahuajiao - Gangbei Port - Boao Port - Qinglan Port - Tonggujiao - Paoling Port - Jiadingjiao - Jimao Bay - Wushizi - Mulantoujiao - Xinpujiao - Lingjiao - Shijiao - Puqian Port - Dongyingsha - Shazhou Port - Shazhoujiao - Haikou and other nearly 90 ports, which provides very important information for the study of Hainan 's ports, fishery resources, geological water quality, maritime transport, private trade and so on.
