You can take the bullet train from Chengdu to Chongqing North Railway Station (about two hours, the fare is in 98 yuan), and then transfer (what is bus No.26 or No.23? I forgot for a moment. Where do you ask? Go to the Automobile Expo Center, then take 6 19 to Zheng Xi, or take a taxi directly. Fast, about 105 yuan! In addition, you can do ordinary fast, but it is slower, the car is not fast, and it is more expensive!

I hope I can help you. Have a nice trip!
