Naturalist Zhili said; Statistics within the four seas, there are 28,000 miles long from east to west, and 26,000 miles from north to south; Among them, there are as many as 8,000 miles of waterways, six grand canyons, as many as 600 large rivers, and almost 3,000 overland roads. Dayu dispatched the walking Taizhang from the easternmost to the westernmost, walking a total of 203,500 miles and 75 steps. The same sect of people who were also good at walking walked from the northernmost to the southernmost, walking a total of 203,500 miles and 75 steps. ...... Kyushu is a large area, with thousands of miles on all sides. Outside Kyushu, there are eight martyrs, and there are thousands of miles in all directions. ... Outside the eight necks, there are also eight hong, which are also thousands of miles away. ...... On the outside of the eight-fold, there are eight poles. ...... Clouds in the eight-pole range will rain to moisturize the whole world. The wind blowing from eight aspects regulates the cold and heat. The clouds in the eight, eight, and eight ze ranges will rain to moisturize Kyushu and make the Chinese wind and rain smooth. The beauty of the East is the jade on the Lu Mountain of the Doctor Mother; The beauty of the southeast has arrows made of mountain bamboo; Southern beauties include rhinos and elephants from Liangshan; The beauty of the southwest is the gold jade produced by Mount Hua; Western beauties include pearl jade artifacts from Huoshan; The beauty in the northwest includes various beautiful jades such as Qiu Lin and Lang Jiu of Kunlun Mountain; The beauty of the north is the tendons and horns of the cattle and horses produced in Youdu; The beauty of the northeast is the fur of tigers and leopards in the mountains; The good things in the central region are Mount Taishan, which produces grains, mulberry hemp, fish and salt. The terrain is basically classified in this way, calling the east-west direction the latitude and the north-south direction the longitude. The accumulation of yang qi in the mountains is a symbol of the virtue of benevolence and righteousness; Water accumulates yin qi and is a symbol of treacherous destruction. The high place represents life, and the low place represents death. The peaks are masculine and the valleys are negative. There are pearls under the round waves and jade under the square waves. Where the water is clear, there is gold, and the abyss where the dragon lives has beautiful jade. Different types of land will have different corresponding yields. Therefore, where the mountain is heavy, there are more boys, and where the water is heavy, there are more girls. ...... Both coincide with the yin and yang qi and echo the type of land. ...... Everything grows in different categories. ......
