What are the characteristics of dragon patterns in the decorative patterns of China porcelain?

In the decorative patterns of China porcelain, the dragon is a symbol of feudal authority, so it often appears on porcelain. Four-series dragon pots of Yue Kiln in the Five Dynasties, white and black flower dragon bottle of Cizhou Kiln in the Song Dynasty, white and plum bottle with blue glaze in the Yuan Dynasty, colorful Yunlong plate with red glaze in Hongwu in the Ming Dynasty and Yunlong jar printed with green glaze in Yongzheng in the Qing Dynasty are all rare examples of dragons. Dragon patterns from the Warring States to the Tang Dynasty are generally decorated in the flow, lifting beam, handle, neck, shoulder and other parts of utensils, and are made into three-dimensional dragon patterns by folding, pinching and clamping. After the Tang dynasty, dragon patterns were mostly decorated in the main parts of utensils, and the methods of expression were characterization, stamping, painting and so on. The dragon patterns of the Five Dynasties are basically animal-shaped, with horns on the head and unparalleled sideburns. The upper jaw has slightly protruding lips, three-toed claws, and some are decorated with moire or wavy patterns and twisted branches and vines. During the Song and Yuan Dynasties, dragons were mostly snake-shaped, with a tapered tail and claws with three toes, four toes and five toes. The flame of the orb spouts from one end, which is mostly used in court and Buddhism. In the Ming and Qing Dynasties, the dragon pattern was snake-shaped, with sideburns and five-toed claws.
