1. Peel the onion, rinse it with water and cut it into horns.

2. Wash the green pepper with clear water, cut it into small pieces and remove the seeds. (note: spicy stems don't go)

3. Wash celery with clear water and cut into oblique sections.

4. Wash tomatoes with clear water and cut them into small pieces.

5. Wash the cabbage and cut it into small triangular pieces.

Put the above five vegetables into a large pot, add water and simmer for about 3 hours, leaving soup, which can be strong or weak. You can use salt to make your favorite taste, but you can't put animal oil.
