Are there many Chongqing people in Xi?

Not too much. Many of them are concentrated in vegetable or fruit wholesale markets.

Climate: Chongqing is definitely more suitable for Jiangsu people; Transportation: It's all the same, but Xi 'an is a transportation hub, so it's convenient to go anywhere.

Diet: Xi 'an's diet is very inclusive, bringing together Sichuan, Shandong, Jiangsu, Zhejiang, Hunan, Guangdong and Northeast cuisine. Don't worry about accommodation, let alone food.
