There are two main rules of wearing robes in Buddhism. First, colors are not allowed to be colored or solid. Second, all new clothes must be painted with another color in one place, so as to destroy the neatness of clothes and avoid coveting to wear them. This is called "bad color" or "clean point".

Although there are many choices for the colors of monks' clothes, avoiding coloring and solid colors, red was often used as the color of clothes in the early days of Buddhism, so when Buddhism first entered China in the Han Dynasty, monks also wore red clothes.

The climate in the north is cold and the monks don't have enough clothes, so the monks in our country wear another kind of uniform in the cassock, which is made up of the clothes of ancient laymen with a little change. The color of the uniform was stipulated by the Ming emperor. Buddhist monks' uniforms are brown, missionaries' are blue, and legalists' are black. After the Qing Dynasty, there were no formal regulations, but after the revival of lawyers in the early Qing Dynasty, the uniforms of ordinary monks were all yellow.

During the Three Kingdoms period, the monk's clothing color was influenced by the Taoist's clothing color, and gradually tended to be red (that is, there was a slight red meaning in black), so at that time, monks began to be called "clothes" or "flow".

In the Tang Dynasty, Wu Zetian gave nine people, including Samana Fallon, purple cassock according to the rules of the Tang Dynasty. Therefore, in the Tang and Song Dynasties, he was always proud of giving purple cassock. On the other hand, scarlet cassock is the most admired because of its obsession with red.

After the Tang and Song Dynasties, the color freedom of monk's clothes was greater. By the early years of Hongwu in Ming Dynasty, a perfect color system of monks' costumes had been formulated. At that time, Buddhism was divided into three categories: Zen (Zen), Buddhism (Tiantai, Huayan, Faxiangzong) and Buddhism (also known as Fa, engaged in funeral ceremonies and sacrificial ceremonies). It is stipulated that Zen monks should wear dark brown uniforms, green belts and jade robes It is said that monks wear jade uniforms, green tapestries and light red robes; Teach monks to wear soap clothes, black sash and light red cassock.

Extended data:

According to the Buddha's system, there are three kinds of cassock, namely, Antuohui (i.e. five clothes), Yuduoluo monk (i.e. seven clothes) and Sangha pear (i.e. nine clothes), which are called three clothes, and their preparation method is certain. Although there are various opinions about color, it is generally not about color, but about quality. Then the world became so beautiful that the original system was almost lost with yellow, red and other positive colors or gold clothes.

And take the cassock as an example. Because India is a tropical place, most of them are directly lined with cassock, so the Indian monk group only has three clothes. In China, Japan and other places, cassock is worn on cassock or frock, and cassock and clothes are collectively called cassock clothes.

Especially in Antuo, Japan, there will be five cassocks, small five cassocks, three-line five cassocks, seed cassocks (or round cassocks) and 50% cassocks (or folds)

In addition, there are other kinds of cassocks, such as cassocks, remote mountain cassocks and so on. According to legend, the golden dress was offered by the Buddha's aunt Mahabobo to serve the Buddha. Their fate is recorded in the 13th volume of Hanshu agama and the 12th volume of the Classic of Virtues and Fools, but it is not found in the law.
