The second sentence, "Spring Breeze Warms Tu Su", describes people drinking Tu Su's wine heartily in the warm spring breeze, and the third sentence, "Every family's day", describes that the glory of the rising sun shines on every family. Use "_ _" to represent the splendid scene at sunrise, symbolizing the infinite bright and beautiful prospect. In the conclusion, the phrase "Always exchange old symbols for new peaches" not only describes the folk custom at that time, but also contains the meaning of exchanging new cloth for old cloth. "Fu Tao" is a kind of red wooden board painted with gods, which is hung on the door to ward off evil spirits. Every new year's day, take off the old peach symbol and put on a new one.
