                                Tips: 
                                The ratio of sweet and sour is 1:1. If you like sweet, add more sugar, and if you like sour, add more vinegar. Soy sauce is used for toning, so a little bit will do. Salt is added to keep the mouth open, and MSG is used to improve freshness. . It is recommended that the soup be chilled. . As for tomato slices and cucumber shreds, cooked sesame seeds depend on what you like and add them yourself. .
