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

According to the regulations, western judges must wear wigs, which is a bit of a story. Wig fashion began with King Louis XIII of France, especially in the17th century. It is a symbol of social status. Many industries also use it as a symbol. However, the French Revolution and the American Revolutionary War washed away the muddy water, and the revolutionary party changed its customs and swept away the signs of various status classes. At present, only the court systems in Britain and a few countries keep this habit. Judges in Britain and former Commonwealth countries and regions including Hong Kong wear a shawl wig on their heads, lawyers wear small wigs, and judges and lawyers wear robes, usually black. The trial under this decoration gives people a sense of ceremony. It is said that by wearing a black robe and faking the law, a judge can hide his true colors, get rid of selfish distractions and become the embodiment of the rule of law, truth, goodness and beauty.
