There are two main reasons for the decrease of foreign population in Ke Qiao in recent years:

1. The number of small and micro-processing private enterprises in Ke Qiao has decreased, which makes it difficult for migrants to find jobs and cannot live locally.

2. Ke Qiao's basic education resources are relatively insufficient, and it is too difficult for children to study, which also makes the living cost of migrants in Ke Qiao relatively high, making it difficult to retain talents.
