How to go to Shenxian Chi by bus from Songpan or Chengdu

Leaving from CD City, you can take a long-distance bus at Xinnanmen Bus Station or Chadianzi Bus Station to Jiuzhaigou County. I remember direct buses to Shenxianchi at local bus station are available. Also a friend told me that in front of Jiuzhai Tiantang near the valley, a bus scheduled at 9:00am leaves for Shenxianchi every day. Hope help!

Thank you so much
