How many buses can Zhaoqing take to Dinghushan?

I only know 2 1 and 3! 2 1 Road to the entrance of Dinghushan Scenic Area! Very convenient! I take this bus to Dinghushan! You can take this bus from Duanzhou No.3 Road to Dinghu Lake! Because the 2 1 road is "Paifang to Dinghushan", it seems to be a tourist bus! I want to know where you are. I've been on the No.3 bus, too! But only to the intersection of Dinghushan! You need to walk for about ten minutes by yourself!
