Native to the Mediterranean and Central Asia. It was introduced into northern India, and then into China through Central Asia and West Asia. Now it is planted all over the north and south. At first, it mainly fed on tender beans, and later in the south, such as Guangzhou and Meizhou, Guangdong, it was also called pea tip, pea seedling, tender bud and tender stem and leaf. Now it is regarded as a daily good dish in the country.

It is a plant that can not only pick the tip of beans but also harvest pods. Picking bean tips 30 days after sowing. Widely cultivated in Sichuan, Yunnan, Hubei, Guangdong, Shanghai and other places. Pea tip stems and leaves are tender and delicious. It is a high-grade green vegetable with excellent quality, rich nutrition, safe eating, rapid growth and no pollution, which is favored by consumers and hotels.

Since ancient times, Hanzhong has been full of gold. In the endless cauliflower world, green beans are quietly dressing up, sticking out buds and leaves, attracting pedestrians to linger and enjoy themselves. So vegetable farmers went to the fields to pick, vegetable vendors went to the market to sell, and several delicious seasonal dishes were added to the tables of urban and rural people: fried pea tips, roasted pea tips, cold pea tips, pea tip soup, and even noodles with green shoots and green leaves.

In southern Jiangsu, "Pea" reads "Andu" from them, so "Pea Head" is called "Andutou". Pea head has become a must-have dish on every banquet menu. People believe that putting a dish cooked by Andutou on the dining table can bring peace and good luck for a year.
