how do I take public bus from Pudong Airport to Majesty Plaza Hotel 700 Jiujian, Huangpu District?

You can take the shuttle bus line 2 to Jing’an Temple (City Terminal Building). Then take a taxi to the hotel at a cost of NCY20 around.

Or you can choose another simple way. Take the subway line 2 to East Nanjing Road. Take the Exit 4 and walk about 800 yards to the hotel.
