How can I go to Chunxi Pedestrian Road from Lhasa Grand Hotel in Chengdu?

From your hotel, you can take a taxi to get to Sichuan Gymnasium Station where you can take the subway line 1 to Tianfu Square Station and then change to line 2 to Chunxi Road Station.
Then you can find the direction boards in the station to find the exit B to get out of the station and then walk to the Chunxi Road.
