However, Toona sinensis generally germinates before Tomb-Sweeping Day, and the terminal buds can be picked before and after Grain Rain. This kind of first-time picking, called the first-time Toona sinensis bud, is not only tender but also full of fragrance. For a long time, people have become accustomed to eating Toona sinensis. As early as the Han Dynasty, our ancestors ate Toona sinensis, and Toona sinensis was once used as two major tributes in the north and south together with litchi. Song Zan said, "Toona sinensis is solid and leaves are fragrant." Spring and March are the seasons for eating Toona sinensis. Therefore, Toona sinensis is best eaten in spring.
