The reasons why there are few people in Guangzhou Taihe are:

1. The local population birth rate in Taihe is low. Due to the low level of local economic development, people do not invest enough in children's education, which leads to the low birth rate, thus the population of Taihe is decreasing.

2. The phenomenon of local population outflow in Taihe is serious. With the economic development, more and more people, especially young people, will go to other places to work and live, which will lead to a decrease in the population of Taihe.
