Early Chaoshan winter vegetables were all trafficked from Tianjin. During the period to War of Resistance against Japanese Aggression, Lianyang Fair Sufu Factory in Chenghai County hired Tianjin technicians to start producing winter vegetables. Since then, Beijing-Tianjin Chinese cabbage (also known as winter vegetables) has also been introduced to Chaoshan for planting. Chaoshan winter vegetables are still rich in Lianyang area, and are famous for their delicious taste. Every year, a considerable number of them are sold all over the world.
