from Huangshan to Guilin by train

I thought Train K155 will depart from Huangshan 23:04 and arrive Guilin 16:14 next day. Is Train K155 change the schedule and not stopping Guilin anymore? If so, any other way to get to Guilin from Huangshan by train on 6/15/11. Looking to book 4 soft sleepers including 2 children age of 8 and 10 under 140cm tall.

Thanks for your help.
