I heard there's a night bus leaving from Chengdu Chadianzi station to Jiuzhaigou

so I asked a bus agent and JZG official website and they said there's no night bus. All buses leaving in the morning.

Can anyone here confirm that there's a night bus to JZG? Did you take the night bus or just heard from someone else?

I plan to arrive in Chengdu October 21st in the afternoon and want to book the ticket for 23rd. I don't know if this is going to be too late to guarantee my seat since the night bus might be in high demand.

Thanks
