If you travel to China, and if you depart from Hong Kong or Macau, it is likely that you will use the train station in Guangzhou, or Dongguan in southern China. Note that, these two cities have two train stations, both with the newer one at the eastern part of the city, called Guangzhou East Station and Dongguan East Station respectively.
The original and old stations in the cities are simply called Guangzhou Station and Dongguan Station. As mentioned in my previous post, do pay attention to which station you will land at or get to. Otherwise, you will have big troubles, especially when you are catching a train.
The two train stations in Dongguan are near, with 10 minute taxi ride between each other. But in Guangzhou, the two train stations are rather apart. Fortunately, at both stations, there are metro stops. You can easily go from one to the other.
