Personal suggestion: don't take the dragon bus express, but I'd rather pay tens of dollars more to take a taxi to the bus station. You don't try their service attitude, you will know whether it is worth tens of dollars. The usual fare for the high-speed bus on the round-trip special line from Guangzhou to Puning is 100 yuan.
Puning Liusha Station to Guangzhou Tianhe Bus Station
Puning station leaves for Guangzhou Tianhe Bus Terminal every hour, and the fare is 130 yuan.
