What is the history and future of hangers?

The clothes hanger was invented by a worker named Albert Parkhouse. At that time, he was a blacksmith who worked as a lampshade in a small handicraft company in Michigan, USA. One day, he found angrily that the clothes hooks in the cloakroom of the factory were all occupied. He angrily took out a lead wire, bent it into the shape of a coat shoulder, and put a hook on it. This invention was patented by his boss, which is the origin of the clothes hanger. Clothes hanger is a kind of furniture which appeared earlier in China. The Zhou dynasty began to implement the ritual system, and the aristocratic class attached great importance to clothing. In order to meet this demand, shelves specially used for hanging clothes appeared earlier. Clothes hangers in different dynasties have different forms and names. During the Spring and Autumn Period, clothes were hung by wooden poles with horizontal frames, which were also called "trusses" and "wooden spreads". In the Song Dynasty, the use of clothes hangers was more common than that of the previous generation, with vivid data. The clothes hanger in the mural of Song Tomb in Yuxian County, Henan Province, is supported by two columns, and the two ends of the crossbar extend out of the columns, and the two ends are slightly upturned to make a flower shape. Two horizontal wooden piers are used to stabilize the columns at the lower part, and a horizontal beam is added between the two columns at the lower part of the upper railing for reinforcement.
