The deepest feeling is: it is too difficult to climb! After three hours, I arrived at 4999. I was not allowed to go to 9999 after 3 pm. Fortunately, I didn’t go up. I came back and was paralyzed for almost five days. I had to go to 9999 in the morning and prepare dry food (there is no food on the mountain). The waterfall is manually controlled. The water volume is put down from the mountain reservoir. Don't drink water and don't wash your face. It's good to go leisurely. If you have a big goal, you must be mentally prepared.~
