What is the most economical way to travel from Baotou, Inner Mongolia to Lijiang, Yunnan?

Option 1: You can go to Beijing by train, because the air tickets in Beijing are still relatively cheap, and then Beijing flies to Kunming, and you go to Lijiang by train from Kunming. Option 2: You fly directly from Beijing to Lijiang. Scheme 2 takes less time than scheme 1, which saves the fatigue of the journey. Snacks in Lijiang are relatively cheap and accommodation is not expensive. Two people go to see how you spend it. According to the general consumption, each person spends about 5000 yuan.
