Ms. Deng told reporters that the small bag of purpura sold 5 yuan and 6 packages in the mouth of the vegetable farm, and the large purse she had bought before she bought was 2.5 yuan a pack.
when she went home, Ms. Deng put the newly bought seaweed in the clean water and planned to make a seaweed soup at noon.

She quickly rejoined a bowl of clean water to wash the purple vegetables, "but repeated washing several times." The water is still pink. She never bought such a large bag of seaweed before.
