hallo .. i want to go to jieyang can i take a bus from hongkong?

Sorry but there is no bus from HK to Jieyang. But you can take East Rail Line to Lok Ma Chau and pass through Futian Port to Shenzhen.
Then, take metro line 4 and transfer to line 1 at Convention & Exhibition Center. Get off at Zhuzilin and leave from Exit D, you will see Futian Bus Station.
At last, you can take a regular bus to Jieyang, the buses leave at 9:50, 13:10, 15:15 and 17:40.
