1. In ancient times, China was divided into nine states. The story is not the same. Book - Yugong" for 冀、衮、青、 徐、扬、 荆、 豫、梁、雍; "尔雅-释地" has 幽、 营州而無青、梁州; "周礼-夏官-职方" has 幽、并州而無 徐、梁州. Later, the term "Jiuzhou" was used to refer to the whole world, the whole of China. Chu Rhetoric - Li Sao (楚辞-离骚)："Thinking about the vastness of the nine states, is it not only that there are women in them?" Song Lu You, "Showing My Children": "In death, I know that all things are empty, but I am sad that I cannot see the same in the nine states." Gong Zizhen, Qing Dynasty, "Miscellaneous Poems on the Occasion of the Birthday of the Emperor," No. 125: "The nine states are angry with the wind and thunder, and outpatient outpatient outpatient outpatient outpatient outpatient outpatient outpatient outpatient outpatient outpatient." Guo Moruo, "In Praise of Lei Feng": "Twenty-two years have become permanent, and all the people in the nine states look up to the martyrs."

2. It refers to the nine states. China is only one of the nine states. During the Warring States period, Zou Yan called China "Chixian Shenzhou" and said, "If there are nine states outside of China, such as Chixian Shenzhou, it is the so-called nine states. See the Records of the Grand Historian (史记-孟子荀卿列传). Huainanzi - topography training: "What is the nine states? Southeast Shenzhou is Nongtu, due south Jizhou is Wotu, southwest Rongzhou is Taotu, due west Trapzhou is Jintu, due center Jizhou is Zhongtu, northwest Taizhou is Fertilizer, due north Clear State is Chengtu, northeast Pouzhou is Yintu, and due east Yangzhou is Shentu." Yang Shuda thought the cited nine states, since the center of Jizhou and "Yugong" nine states of the Jizhou even the same, the rest are name differences; its name Southeast Shenzhou, and Zou Yan said that the name of China is the red county of Shenzhou; suspected that the article is taken from Zou Yan's book, the cited nine states of the nine states of the nine states called by Zou Yan. The name of the nine states cited in the book is that of the nine states called by Zou Yan.

Liu Xiang of the Han Dynasty said in "Saying Yuan - Discriminating Things", "Within the eight wastes there are four seas, and within the four seas there are nine states." According to Tang Dynasty exegete Yan Shigu's explanation, "The Eight Deserts is the eight barren and extremely distant lands." What about the Four Seas? Er Ya - Interpretation of the Earth says: "Nine barbarians, eight Di, seven Rong and six barbarians are called the four seas." Some people believe that the Four Seas are the four seas surrounding the state of Kyushu. The Rituals and Sacrifices mentions the East Sea, the West Sea, the South Sea and the North Sea as the "Four Seas". "four seas", but not clear sea. Hong Mai of the Song Dynasty in the "Rongzhai Suibi" said "four seas one", that the "four seas" are connected as one.

There are also many references to the Five Lakes. "Water Classic - Shinshui" that "five lakes are Changdang Lake, Lake Taihu, Lake Shuo, Lake Gui, Lake Ge Ge". And Tang Sima Zhen thinks "with area (i.e., Taihu Lake), Tao Ge, Peng Li, Qingcao, Dongting Lake" is "five lakes". However, modern people put "Dongting Lake", "Poyang Lake", "Chaohu", "Hongze Lake", Poyang Lake", "Chaohu", "Hongze Lake" and "Taihu Lake" as "Five Lakes".
