1. Soaking in water: cut bamboo shoots into pieces or segments, soak them in clean water for 2-3 hours, and then rinse them with clean water.

2. Blanching: Cut the bamboo shoots into pieces or sections, blanch them in boiling water for 1-2 minutes, and then rinse them with clean water.

3. Cooked: Cut the bamboo shoots into pieces or segments, cook them in boiling water, and then rinse them with clean water.
