Why is Shentong Express so slow recently?

The latest answer, I have a deep understanding of the speed of Shentong Express. Express delivery is by air. Everything I bought was sent from Wuhan to Fengqing, Lincang. The specific routes are: Wuhan to Kunming by air, Kunming to Lincang by air, Lincang to Fengqing by road. Then the problem is coming. It takes about 2.5 hours to fly from Kunming to Wuhan, which is 1700 kilometers. Then my things flew from Wuhan to Kunming, and it took me two days to fly to Kunming, Nima. Is this freight or travel around the world, or a time wormhole? Khan, and then it takes 45 minutes to fly from Kunming to Lincang, which is less than 700 kilometers. Well, flying to Lincang at 9 am and noon, the problem comes again. Lincang to Fengqing is only over 200 kilometers, and it takes only three hours to drive by yourself, but the courier won't leave. Because I was airsick for a few days, I have to stay in Lincang for one day and stay for one night, and then I will see Feng Qing off the next day. It is very special to drive back and forth 3.4 times a day from Lincang to Fengqing. I suggest you change it. If you think the answer is good, just push me up. I don't want to delay. I want to be sincere.
