Where must I go to travel to Yunnan?

If it is my first time to Yunnan, I suggest go to dali and Lijiang, the two most mature cities, because these two cities developed tourism earlier, and tourism is an important pillar industry in Yunnan. The transportation and tourism services are perfect and the scenery is good. I believe I won't be disappointed with the travel in Yunnan. To travel to Yunnan, you usually have to go to Kunming first. Kunming is the transportation hub of Yunnan Province, and it is on the same tourist line as Dali and Lijiang. From Kunming to Dali, you can take a train or a bus, which is very convenient. Of course, there are planes, because the distance is too close and it is too troublesome.
