How about collecting waste products in Wuhan

Not bad. The purchase price of waste products in Wuhan is generally higher than that in other regions. Many waste treatment plants in Wu Hanyou are recycling a lot of waste products. The local living standard is also relatively high, so consumers have greater demand for all kinds of waste products, and businesses can charge higher prices. Wuhan, referred to as Jiangcheng for short, is the capital of Hubei Province, the only sub-provincial city in six central provinces, a megacity, a central city in central China and an important industrial base in China.
