There are five flavors in the world: sour, sweet, bitter, spicy and salty, and then there is a compound flavor. As you just said, hemp belongs to a compound taste, and incense also belongs to a compound taste. There are spicy, hot and sour, sweet and sour, and so on, such as sauce pig's feet, sauce pig's head meat, and roast chicken. With various Chinese herbal medicines, it becomes very fragrant after a long time. There are five flavors in itself, but in the progress of human beings, due to human changes and additions, various compound flavors have appeared. Thank you for your adoption.
