1. Go to the ferry terminal in Qisha, take the ferry to Nansha Port, 8- 10 yuan to Jinzhou District subway station, and then take the subway directly to higher education mega center south or North Station. This is the cheapest and most recent method.
2. Take the through train from Shatian Station to Guangzhou, and the next station is directly like the subway, as above.
I don't need to teach you how to take the subway ... I have a route map, so you can look at it yourself or ask the staff.
