What if the peach blossom cracks?

The maintenance method is as follows: 1 Soak the selected peach hairpin blank in water completely. 2. Boil the soaked peach hairpin in water with caustic soda. 3. Then continue to cook in boiling water for four to five hours, and immediately soak in clear water after cooking until the peach hairpin does not absorb water. 4. Take out the cooked mahogany hairpin, put it in a cool and windless place, naturally cool off some water to make it basically set, and then put it in a ventilated and dry place to dry naturally. 5. Then tie the dried peach skins into bundles and dry them. The treated peach wood has beautiful color, no cracking, no deformation and no moth.
