As for why British judges wear wigs, it is said that there are several reasons: the first reason is to protect judges. When civilization began to punish criminals by law, no one was sure to be a villain, especially to sentence someone to death, so they wrapped themselves in masks and wigs. The criminal doesn't know who made the final ruling, which shows that the judge himself has no enmity with the criminal, but only exercised the power entrusted by law. Later, they only wore wigs. At that time, nobles usually wore wigs on official occasions, and judges wore wigs to show their solemnity, which showed that judicial behavior was a formal behavior with strong ceremony, not a casual behavior on the street or on the kang. One more thing, wearing white and gray wigs makes people look older. The so-called world is well-informed and well-informed.
