How to get from guangzhou east railway station to Guanyin in Nanhai, Foshan?

I suggest you look at the suggestion of Foshan people: The South China Sea Guanyin you mentioned should be the South China Sea Kannonji.

Take the subway and transfer to 1 line in BC.

Subway route: Take the 1 line in the direction of Kengkou to the terminal, transfer to Guangfo subway, get off at Zumiao Station, take the No.2 bus at the entrance of Zumiao, and get off at Cannongji, Taoyuan, Nanguo.

Bus route: 1 line, get off at Kengkou Station in the direction of Kengkou, cross the overpass, transfer to Guangfo bus, and take Zumiao. Take bus No.2 at the entrance of the ancestral temple and get off at Kannonji in Nantaoyuan.
