How to take a bus from Guangzhou Jie Fang Nan Lu to Humen, Dongguan? How long does it take?

You can walk to reach Jiefang Middle Road to find Gongyuanqian Subway Station of line 1. Then take the line 1 to reach Tiyu Xilu Station where you can change to subway line 3 to take you to reach Tianhe Bus Terminal.
At this bus terminal, you can find direct buses to reach Humen.
The bus for Humen takes about a hour and a half.

Thank you for the info.
