Why do Chengdu people run Dujiangyan for the aged?

I have lived in Dujiangyan for three years. Compared with Chengdu, some of them will never reach the convenience of life in Chengdu.

The cost of living is not lower than that of Chengdu, which is ok for a person who doesn't have too many living requirements, but I don't think it is necessary to sell the house in Chengdu to live. 1, climate, pleasant climate, four distinct seasons, no wind below zero tomorrow, almost no need to turn on the air conditioner in summer. 2. The environment is very good. The buildings in Pingyuan City and Dujiangyan City are limited in height, and the whole city can see mountains and water. Good vegetation, park 100 meters. Hygiene is well done, and no garbage can be seen. Dujiangyan is near Aba in the north. Aba has many green fruits, such as red plum, pipa, cherry and golden apple. These fruits are pollution-free, delicious and fresh. Very important to life. 4. It is convenient for medical care and old-age care. Dujiangyan is near Chengdu, and it only takes 1 hour to go to Huaxi by car. The medical level of Dujiangyan Medical Center is also very good.
