Why is the Forbidden City a red and yellow plot and an example in life? On the implication of red in China folk customs.

1. yellow, regarded as a positive color in China since ancient times, represents the central position in the theory of five elements (fire, Shui Mu and Jindi) (the central part belongs to soil, and the soil is yellow), and "soil is born by all things and used by people" (Biography of Shangshu). The people of China have lived in the Loess Plateau for generations, and they have special admiration and attachment to the loess land that provides them with food, clothing, housing and transportation. Naturally, the color of loess is worshipped exclusively by people. Therefore, yellow symbolizes dignity. According to the section "Forbidden Yellow" in the Wild Guest Series by the poet Elvis Presley in the Song Dynasty, "At the beginning of the Five Virtues in Tang Gaozu, the Sui Dynasty was adopted, and the emperor always wore yellow robes, so scholars were forbidden to wear them, but yellow clothes were forbidden from now on." It can be seen that at the latest in the Tang Dynasty, yellow has been stipulated as the color representing the royal family, and no one else is allowed to use it in clothing. In the Song Dynasty, the imperial palaces of feudal emperors began to use yellow glazed tile roofs. In the Ming and Qing dynasties, it was clearly stipulated that only palaces, tombs, altars and temples ordered by the emperor were allowed to use yellow glazed tiles, and other buildings were not allowed to use them without authorization, otherwise they would be "guilty" and executed.

2. Red has always been regarded as a festive color in China, full of solemn, joyful and rich meanings. It is said that hundreds of thousands of years ago, our ancestors cavemen liked to decorate their homes with red. In order to show the nobility and wealth of emperors, red has been widely used in palace buildings since the Zhou Dynasty and has been handed down.
