The content of the silk painting of the Warring States Period, the Painting of Dragon and Phoenix, reflected the ancient Chinese thoughts of dragons and phoenixes, and the mutual promotion and restraint of the five elements. In this painting, the characters are depicted as dragons, phoenixes, and flowers of five different colors. These flowers represent the five elements of the five elements: metal, wood, water, fire, and earth. In traditional Chinese culture, dragons represented fire phoenixes, wood flowers represented water, earth, and metal. According to the theory of mutual promotion and restriction of the five elements, the five elements interacted with each other to form a series of mutual promotion and restriction relationships. For example, metal could produce water, water could suppress fire, fire could produce earth, earth could produce metal, metal could produce wood, and so on. This thought reflected the ancient Chinese's understanding of nature and the universe, as well as their views on human society and life. In addition, the flowers and figures in the silk painting of the Warring States Period also showed the pursuit and imagination of the ancient Chinese for beauty and art.
