Actually, they are not the

same question. The development of Chongqing was always suppressed by Chengdu in the past 40 years, even when Chonqing become directly managed city, Sichuan still gave Chongqing a very heavy load of poor district. No mention to Sanxia Project of later.
Actually, what I mean is Chonging and Sichuan are brothers, but not father and son!
