I started from Zhengzhou and wanted to visit Chongqing and Chengdu. Are there any good tourist routes to recommend? Is it better to go to Chongqing or Chengdu first?

Let's go to Chongqing first, fly to Chongqing Jiangbei Airport, and then take the airport bus to downtown. There are many things to do in the suburbs of Chongqing, but the main city has no good natural scenery, such as Ciqikou, Foreigners Street and Geleshan muck cave. . . These are not very funny, and there are surrounding scenic spots: Wulong fairy mountain, Wansheng Black Valley, Shilin, Beibei Jindaoxia, Jinyun Mountain and Jiangjin Simian Mountain. When you go to Chengdu, you can take buses of various classes at Caiyuanba and Chen Jiaping. The price is between 1 10- 130, which takes about 4 hours. There are also many kinds of trains, and the price is uncertain. The bullet train only takes more than two hours and the price is uncertain. See if you want to take a train or a bus. The main attractions in Chengdu: Jinli, Du Fu Caotang, Jinsha Site, Happy Valley, Wuhou Temple, Qingyang Palace and Kuanzhai Lane. . . Around Chengdu: Huanglongxi, Luodai, Sansheng Township, Wenjiang National Scenic Area, Dujiangyan, Qingcheng Mountain, Xiling Snow Mountain, Pujiang Shixiang Lake, Qionglai Tiantai Mountain and Longquanyi. . There are many further places, such as Mount Emei, Leshan, the Sea of Death and Jiuzhaigou. . . . . . . . . Then fly back to Zhengzhou.
