Shanghai and the southeast coast
The primary characteristics of this region include water, marshes, and hot and humid summers, which are shared by the entire Yangzi valley. The influence of the Pacific Ocean, as well as access to it, distinguishes the area. The adjacent mountains are ideal for crops such as rice, shrimp, and ducks. Through the opium war and the “Treaty Ports” of the eighteenth century, this was the first region to suffer the effects of the west.
This region’s major city is Shanghai. It is a prosperous port and a center for steel, telephones, vehicles, power generation equipment, petrochemicals, and electrical appliances.
The Yangzi valley and its tributaries and lakes are the centers of life and commerce in the region. Mountains separate it from the other regions. The Yangzi River has significant wetlands in this area; summers are hot, humid, and rainy along the river, while winters are brief but frigid.
Historically, the Yangzi valley has been a significant food producer. The river has always been a focal point of commercial activity, bringing trade and influences from far-flung lands. Life and culture in this area are dominated by fishing and boat commerce. Cities like changing, Wuhan, and Nanjiang are propelled by economies based on water-borne transportation and trade rather than agriculture or even food processing. Because the river provides a cheap mode of transportation, major manufacturing areas have sprouted up along its banks.
The Sichuan Basin
The Sichuan Basin is separated into two parts
Chengdu and Chongqing. The area is surrounded by high and steep mountains. The Yangzi River, which runs through the famous Three Gorges, is the primary route to eastern China.
Extremely rich soils are formed primarily from historic lake-side mints. Farmers can rely on a variety of food crops and specialty in addition to numerous crops each year. “Sichuan was the first province to proclaim independence and the last to be reunited after peace,” as the saying goes. This region is a well-protected productive setting that is contiguous to almost every region in ancient China.
Sihuan is well-known for its tea, silk, flowers, medicinal plants, and diversified wildlife, which includes pandas, deer, and tigers. Tourism is very important to the economy of Sihuan.
Southwest uplands

It receives a lot of rain because it is adjacent to the tropical cyclones of the Bay of Bengal and the South China Sea ( often causing erosion or denuded slopes). During the Mongol Yaan Dynasty, this territory first entered the Chinese domain (127-1368). Its history shows both its harsh environment and its proximity to current Southeast Asian countries and peoples. The region is well-known for its rice farming, winter wheat, tea, and bean production. The area is also valuable for opium growing, which arose as a result of Britain’s opium war with China
