What line should i take if i want to travel from the Pudong airport to the Howard Johnson Plaza hotel at 595 Jiu jiang Road.

The airport shuttle bus cannot take you to your hotel directly.
If you want to take, you can take the shuttle bus line 2 to its terminal at Jing'an Temple and take a taxi to your hotel.
Or you can take the local subway line 2 to People's Square Station and get out of the station from Exit 20. Then walk along the Jiujiang Road to your hotel easily.
