From Peizheng Ave to line3 Ren He station in Guangzhou

Hi, Grace.
For the Peizheng Avenue, do you mean the avenue before the Peizheng College? If so, the road is about 35km to Renhe Station, traveling in about 2 hours. You need to walk to Pei Zheng Da Dao Kou Station to take the bus line 713 to reach Xin Hu Da Sha Station, where you can change to bus line Hua 1 to reach Ren He Xu Station. After that you can walk to the Renhe Station.

The Vanguard Mall in Huadu is on Yunshan Avenue, far from the Peizheng Avenue. From the Vanguard, you can walk along the Huacheng Road to reach Heng Tan Shi Chang Station, where you can take the bus line Hua 1 to reach Ren He Xu Station. After that, you can walk to the subway station.
