Regional advantages of Hubei-Huang Yangtze River Bridge

China, a vast country, is a bridge connecting the North and the South and the East and the West. Influenced by its natural geography and humanistic society, it has formed its own relatively independent style and characteristics according to local conditions. For example, the Central Plains and the Yellow River Basin in the north have relatively flat terrain and few rivers and waters, so people rely on mules, horses and carts to transport materials. Therefore, most of the bridges here are Guan Dan's majestic stone arch bridge and Liang Shi bridge, so that ships can pass under the bridge; In the northwest and southwest regions, it is difficult to build piers because of the high mountains and steep valleys. Therefore, rattan, bamboo cable, logs and other mountain materials are often used to build rope suspension bridges or outrigger wooden beam bridges. The coastal areas of Lingnan, Fujian and Guangdong are rich in hard granite, so stone bridges abound. In Yunnan minority areas, unique bamboo bridges can be seen everywhere because of the abundance of bamboo. Judging from the style of the bridge, the bridge in the north is as rough and simple as the northerners; Bridges in the south are as smart and light as southerners. Of course, this is also closely related to physical geography. For example, the rivers in the north have changed greatly due to the bullying of water flow and the impact of mountain torrents and ice, so the bridge must be thick and stable; However, the South River is gentle and easy to navigate, so the bridge is slender and beautiful.
