May I know which wharf is nearest from Tee Mall/Tianhe, Guangzhou? How do we get there by subway?

Tephy, the nearest wharf is the Dashatou Wharf. From Teemal, you can take subway line 1 from West Tiyu Road to Dongshankou and then transfer to line 6 for one stop to Dongh; leave from Exit A and walk southwards until you reach the East Yanjiang Road; then, walk westwards for a few yards and you will reach Dashatou Wharf.
As I know, there are many schedules and you can totally buy tickets when you arrive the wharf.

Thanks so much!!
