There are few vegetables in ancient times, and there are five kinds of vegetables common in Chinese characters: sunflower, epimedium, leek, fermented grains and water chestnut. The sunflower is winter sunflower; Huo is the tender leaf of soybean seedlings; Leek is leek, and its ancient name is still used today; Fermented grains are Chinese cabbage; Shepherd's purse is shepherd's purse. During the Han Dynasty, Zhang Wan went to the Western Ocean with spinach and carrots. Cowpea (long bean) and eggplant were introduced from India in the Han Dynasty, and lettuce was introduced in the Five Dynasties, which was probably the main vegetable on the table of China people before the Tang Dynasty. Later, especially after Columbus discovered the New World, more vegetable varieties were discovered, such as tomatoes, peppers, pumpkins, sweet potatoes, etc., and cauliflower, cabbage and other cabbage vegetables were introduced from Europe.
That's about it.
