During the Tang and Song Dynasties, the color of turquoise was regarded as the color of clothes worn by people in Park Jung Su. In the Tang Dynasty, local officials "did not punish criminals with sticks, but made them wear blue headscarves to humiliate them" (Lu Wenjian), and according to the seriousness of the case, "the number of days is equal, and they will be released when they are full". Shen Kuo wrote in Meng Qian's Bi Tan: "There are children in Suzhou who don't show off, and there are green scarves under their gauze hats. Sun Bochun knows the state:' What's the difference between using green towels and selling them?' "This shows that in the eyes of people in the Tang and Song Dynasties, people wearing green and blue are the lowest-level people.
Since the Yuan Dynasty, clothes in various colors of green and blue have been restricted to "prostitutes" and "musicians". "Yuan Zhang Dian" stipulates: "Prostitutes wear soap shirts and horn towels; The parents and relatives of prostitutes are all men, wrapped in green headscarves. "
In the third year of Hongwu (1370), Zhu Yuanzhang issued a decree: "A musician in a teaching workshop should wear a swastika scarf and tie a lamp line, and a prostitute should be crowned with soap, so he should not be the same as his wife." At the same time, it is also stipulated that "all workshop masters will wear green towels, while others will bring them from Shu Ren". Zhu Yuanzhang made it clear that men in prostitutes' homes must wear green towels, red kidneys and leather shoes with pigs. They are not allowed to walk in the middle of the road, only allowed to "stand aside" on the left and right sides.
At first, the word "their jobs" did not refer to official hats, but to gauze hats that all emperors, officials and ordinary people could use. "Their jobs" originated in Liu and Song Dynasties in the Southern Dynasties. At that time, it was made of black yarn, white yarn and even variegated yarn. Its shapes are different, some are rolled into lotus leaves, some are like tall houses, and some still have two black "ears".
In the Sui Dynasty, as a "spy" hat, the "black hat" was also an emperor, a noble minister, and a hundred officials and scholars. In the early Tang Dynasty, the "black hat" was once a special hat for emperors and crown princes. After Li Shimin ascended the throne, the imperial edict "official position" was worn by the emperor, hundreds of officials and ordinary people. Therefore, in the Tang Dynasty, the "black hat" was just a daily hat. Du Fu once said in a poem: "It's better to watch a white rabbit without sleep than to leave a black veil." He said he couldn't sleep at night and looked at the moon. I don't know how many times the moonlight reflected on his work. But Du Fu had no official position at that time.
