First lay it flat with the side with the trademark facing up (it will be inside when you fold it later). At this time, the flat hat looks like the word "山", and then put it in the middle. After folding down the part with the twist buckle, there are still two legs left on the left and right sides. They can be buckled together on the twist buckle just folded over. The back part is enough. Then turn it around and fold the front one. Fold the lower part upward and then adjust and repair it yourself!
