how can I take the airport bus 's ticket from huachen hotel to hangzhou international airport?

From Grand Metro Hotel to the airport, you can walk west about 700m to take Metro Line 1 from Longxiangqiao Station to East Railway Station. Get out of the Exit E and walk northeast about 500m to take a shuttle bus to the airport. The tickets office is near the city terminal where you get on bus. You can follow the signs to find the location or just seek help from staff of the railway station.

thank you so much
