I have one day in Chengdu. My friend and I want to combine seeing the pandas and the giant Buddha.

Well, I'm afraid that one day is not enough for you to tour around Big Buddha Scenic Area and Panda Base. Generally speaking, you need to spend one day to visit the mountain. In the next early morning, you can start off and see the cute pandas. In addition, for seeing pandas, you can go to Chengdu Research Base of Giant Panda Breeding or Dujiangyan Panda Base. Have a nice journey!
