How can I get from Chengdu Tianfu Square OR South rail station to airport?

1. From Tianfu Square, walk south around 300 yards to get to 1st Section of South Renmin Road. Then take the airport shuttle bus line 2 to get to the airport.
2. From South Railway Station, take metro line 1 to Shijicheng Station, Exit C2.
Then walk north around 400 meters and find the airport shuttle bus line 4 directly.
Hope helpful!
