Buttons are daily necessities that human beings often accompany. It has been used for more than six thousand years. As early as 4,000 years ago, the Persians, the ancestors of Iran, had made buttons out of stones. In the Zhou Dynasty, China began to adopt the system of coat under clothes. Both men and women wear two clothes, one is the top and the other is the bottom. In North Korea, there are officials who specialize in making dresses, and civil and military officials must wear dresses when doing ceremonies. At that time, the use of clothing was relatively standardized and the clothing system was relatively complete. The word "new" appears in Zhou Li and Li Ji, which reflects the etiquette of Zhou Dynasty. The word "new" is a knot that is tied together, that is, a heart knot. According to my collection of Western Zhou bronze buttons and domestic archaeological discoveries, buttons were used in the Spring and Autumn Period and the Warring States Period. Among the Warring States cultural relics unearthed in Shizhai Mountain, Jinning, Yunnan, buttons with round, oval, animal head and irregular shapes have been made of blue, apple green and light gray turquoise. Each has one or two small holes. Some carved patterns are unique, colorful and have wonderful wax luster. In the collection of buttons, there are still simple buttons made of small stones, shells, animal horns, walnuts and coconut shells. This shows that China people used buttons in the Zhou Dynasty, the Spring and Autumn Period and the Warring States Period. In the middle of the ancient grave era unearthed in Japan, the pattern displayed on the wheel made of human figure shows that the male clothing consists of clothes and skirts, and the clothes are narrow-sleeved tops with buttons on the front chest. It can be seen that the Japanese used buttons before the ancient grave period. /kloc-In the 6th century, China introduced buttons to Europe. At that time, only men used it, and few women used it. Most of them are just used as clothes. In order to show their wealth, some dignitaries make buttons with precious materials such as gold and silver, pearls, precious stones, diamonds, rhinoceros horn, antelope horn and ivory. In France, it is recorded that King Louis XIV made a robe with 1.3 million precious buttons. In my collection, there are precious buttons made of precious materials such as horn, antelope horn, ivory, gold and silver.
