Why do Hong Kong lawyers wear wigs and hats like that in court?

According to regulations, Western judges must wear wigs. There is a story in this. Wig fashion began with King Louis XIII of France, especially in the 17th century, as it was a symbol of social status. Many industries also use it as a symbol. However, the French Revolution and the American Revolutionary War cleaned up the muddy water. The revolutionary party changed customs and swept away all signs of status and class. Now only the court systems of the United Kingdom and a few countries maintain this habit. Judges in the United Kingdom, as well as judges in former Commonwealth countries and regions, including Hong Kong, wear a shawl wig on their heads, lawyers wear small wigs, and both judges and lawyers wear legal robes, usually black. The court opening under this kind of decoration gives people a very ceremonial feeling. It is said that by putting on black robes and fake laws, a judge can hide his true colors, get rid of his selfish thoughts, and become the embodiment of the rule of law and the embodiment of truth, goodness, and beauty.
