Can you only soak the peach blossom hairpin in water to prevent it from cracking?

Soaking peach hair sticks in water alone can't prevent them from cracking.

Soaking in water, sun protection, or waxing regularly can prevent peach wood from cracking. Secondly, soak the fresh peach trees in water, take them out after soaking thoroughly, then add caustic soda into clear water, cook them for four to five hours with medium fire or large fire, take them out after boiling, and immediately soak them in clear water until the fresh peach trees no longer absorb water. Then put the fresh peach trees in the shade to dry, and then tie them into bundles until they are completely dry.
