i am going to jiangmen from hongkong...and wish to go to dongguan after it...are they far apart ?

Hi, Jenny. As I know, there are direct cross-border buses from HK to JM. At HK, you can take the buses at Mong Kok, Jordan Station (beside Nathan Hotel), Exit C of Kowloon Station and so on. The bus journey takes around three hours and a half.

The distance between JM to Dongguan is around 130km and the bus duration is around one hour and half.
