Kunming Train Station

I purchased my tickets online (KM to Li Jiang) and was told to collect at the station. Can you let me know what is the train station's operating hours in KM? I am afraid that by the time we reach the station at 6pm the ticket counter would be closed. Also, what is the actual name of the station?

As an alternative, I was planning on long distance buses to Li Jiang from KM in case we didn't manage to collect the train tickets. Any reliable bus companies that I can look for? Is it possible to only purchase bus tickets on the spot?
