if i get to chengdu in plane at 10, can i be able to visit leshan that same day?

Is it 10:00am? There are high-speed trains at the airport that can take you to LS directly. The schedules are 07:54, 09:13, 11:00, 12:49, 14:24, 15:59, 17:58, 19:08, 19:33 and 21:10. It takes no more than an hour on the way. Upon getting off, transfer to local bus no. 3 to the Giant Buddha. So you can make it on the same day.
