Is there a direct bus line from Dongguan to Guangzhou South Railway Station?

From Changping to Guangzhou South Railway Station, I take the Harmony from Changping to Guangzhou East. 46 minutes. The fare is 54.5 yuan. Then take subway line 1 to the park and transfer to line 2 to Guangzhou South. Watch the time. It takes about one hour and twenty minutes by subway.
