The capital of Ganjiang Province is Jiangzhong City. In the northern urban area of Jiangzhong, there is a slope of about 2 kilometers long. It is a street called Sanchang Street. The origin of the name Sanchang Street is because from the 1980s to the early 1990s, there were three state-owned factories there, namely Jiangzhong Watch Factory, Ganjiang Second Textile Factory and Jiangzhong 321 Auto Parts Processing Factory.The factory areas of these three factories are separated by walls, so it is difficult to separate the family buildings of the factory employees during construction, so they simply mix them completely together.
