Well, there is no direct public transportation between these two places.
You are suggested to take a train from Kunming Railway Station, get to Guilin North Railway Station first. Then take a taxi to Guilin General Bus Station. There are several long-distance buses that can take you to Longsheng County Bus Station directly.
As far as I know, the bus schedules are from 06:00 to 18:00 with the interval of 15 mins. The ticket fare is CNY 13 per person. And the travel time is about 3 hours.
