Jiangmen City has a population of 430,000 and Huicheng City has a population of 280,000, all of which belong to small and medium-sized cities. After the merger, repeated waste of municipal supporting construction can be avoided. At present, the population of Jiangmen District 3 has grown to nearly 1 10,000.

The establishment of Xinhui District can complement each other and improve the administrative level of Xinhui development. Xinhui was established in 2003. Since 2003, the economic development speed of Xinhui has increased year by year, which is the fastest period in Xinhui's history.
