I don't know where you are going. The South China Sea is very big. When you get on the bus and go to the South China Sea, you must pay attention to your wallet and don't talk to strangers casually. If you don't know, ask the driver. You have to have the change ready before you get on the bus.
You can also take Line 3 to Tiyu West Road Station, then transfer to subway 1 Line to Xilang, and then transfer to Guangfo subway. Just change in the subway, you don't need to leave the subway station, and you don't need to pay extra. ) It's 1 line to Xilang, not line 2, remember clearly.
However, the stations from Guangfo Line to Nanhai are all relatively biased. If you take the subway to Guicheng in Nanhai, it is not suitable to take the subway of Guangfo Line to da li, Songgang and Lishui in Nanhai.
