An Binh used to be a small village on the bank of the Red River. Local people mainly worked on farms and grew their own food. Public transport was not very convenient at that time.

Since then, many local people have migrated to big cities. The village has also attracted people to come and start a business here. In addition, new industrial zone has been developed. Local people and residents of neighbouring villages have started working in the industrial zone's factories. The infrastructure has also been improved. Clean water facilities and drainage systems have been installed. A number of high-rise buildings have been buitt. Supermarkets, hospitals, and many other facilities have also been provided.

A large number of young people are unemployed because they lack the necessary knowledge and skills to work in the factories. In addition, the town is getting more and more crowded. As a result, pollution has increased and has sparked concern among local residents and the authorities. Despite al these concerns, the life of An Bin's residents has generally become much better.
