train for Shanghai departs at 8am, do I have enough time to get to train station from paiyunlou

You are advised to spend one night in the hotel near the railway station. From the hotel to the railway station, you have to first take the cable car and walk to the foot of the mountain, and then take the tourism bus to Tangkou where you can take the bus to the railway station. It is quite inconvenient and costs much time. You'd better go to the railway station one day in advance so that you can catch your train at 08:00am.
