                                Tips: 
                                1. Add salt and marinate for 10 minutes to remove the green and astringent taste. You can omit this step if you don't mind.
 2. The vinegar is best to use a lighter color, which does not affect the overall color. Aged vinegar is not recommended because it tastes too strong.
