Hello everybody

I desperately need your help. I'm planning to go to Leshan, Mt. Emei, Bifeng Gorge for visiting the Panda breeding and research center and Shangli ancient town. I have only two days. I will leave from Chengdu very early in the morning so that I can be either in leshan or Emei at 9:30. Can I combine them together in the same day? Is it better to climb the mountain first? Last but not least, I really don't know how to get from either Emei or Leshan to Ya'an city where the Panda research center is. Are there any bus or train connections? Do you know where and when i can get either a bus or a train? How long does it take? Thank you very much indeed for your very welcome and useful replies.
