I have done it from Beijing to Guangzhou by train once, took about 1- 1/2 days.  Left one morning, arrived on afternoon of second day.  Also, have done the Guangzhou - Honk Kong by train, and used an express one (no intermediate stops) and was just ov er two hours.  

Do make sure if you do, that if use Guangzhou, you arrive to the East Train Station (the new one), near Citic Plaza, since it is from where the Hong Kong train will depart.  If you use one of the other two, will need to trans board by taxi, from 30 to 45 minutes depending on traffic, and about 20 to 25 yuan.

thanks fish and happy.

i don't think i'll take train. 20-21 hours thats too long more ever food in train is very bad.

I used Ctrip for flights guilin to Guangzhou, if i wait and watch I have gotten flights for about $2 more than the train.
