Steps:
1. Soak the semi-dried wakame in water and wash it several times.
2. Put an appropriate amount of water in the pot. After boiling, add wakame and blanch it.
3. Wakame is very easy to cook. Take it out as soon as it is boiled. If it is cooked for a long time, it will become sticky.
4. Let cool slightly and cut into sections.
5. Put one tablespoon of light soy sauce, one tablespoon of rice vinegar, one tablespoon of sugar, one tablespoon of oyster sauce and spicy oil in a bowl and stir well to form a sauce.
6. Pour the sauce onto the plated wakame, mix well and serve.
