Is it difficult to buy train tickets from Kunming to Dali?

It's easy to buy it during the day, and it's ok to buy it on the spot. It shouldn't be difficult at night recently, because it's not a long holiday and people are not crowded at all. As soon as the bus leaves the station, everyone can get a ticket of more than 90 yuan. Just ask any policeman. It's very close. Everyone is in 93 yuan. I saw someone hawking tickets yesterday, so I should be able to bargain. The latest bus is around 9 o'clock, so you should stay longer. The cheapest is during the day.
