In terms of per capita GDP, Nanchang is more than twice that of Nanchong.
Nanchang is the provincial capital anyway, at least there will be more beautiful women in this province. I think if I were in Sichuan, all the beautiful women would have gone to Chengdu.
Also, as far as the environment is concerned, although Sichuan was called the land of abundance in ancient times, there have been frequent disasters recently, and it is a bit dangerous to go there.
