Beef is warm, and it is easy to get angry when eaten too much, so it is not suitable for people with weak spleen and stomach or strong fire due to yin deficiency. In order to prevent eating beef from getting angry, beef can be mixed with some cool vegetables, such as tofu, cabbage, wax gourd, cucumber, bitter gourd, tomato, bamboo shoots, kelp, lotus root, mushrooms, water bamboo and so on.
