I want to know the answer to the following question:
Why was the Chongqing Municipality formed?
All the background I'm provided with is that "This changed in 1997 when the Sub-provincial city of Chongqing as well as the three surrounding prefectures of Fuling, Wanxian, and Qianjiang were split off into the new Chongqing Municipality.". Is that enough to answer the question?
Answer: no
