Is there direct transportation from Chengdu airport to Leshan?

Hello,

I will be flying into Chengdu airport & want to go directly to LS after I landed.

In the Chengdu Airport home web page, it shows there's coach service & time table for LS. However, it does not show the coach number other details.

I need to know if is possible to take a direct bus from the airport to LS, or if I have to transfer to another somewhere outside of the airport. Thanks for your help!
