1) I plan to go from hong kong to guangzhou by train on 22 Apr 2011 (easter public holiday), from Hung Hom Station, how to get the right train to Guangzhou East ?

2) During this public holiday 22 Apr 2011, will there be any change to the train schedule from Hung Hom to Guangzhou East ? When can I know the schedule at the earliest ?

3) This train from Hung Hom Hong Kong to East Guangzhou, is it directly in one go, non stop and only stops at Guangzhou East ?
Or is it stops a few times in the way ?
If its stops a few times, is there any way to know when I have arrived at Guangzhou East and need to go down ?
