In fact, Hong Kong's law originated and improved earlier, because Hong Kong's legal system adopts the common law system. British judges always wear wigs in court, which has obviously become a place to study in Hong Kong.
British judges wear wigs for various reasons. After all, judges are used to punish and sentence criminals, so they are also afraid of criminal retaliation. If you wear a wig at this time, it can effectively make criminals unrecognizable. This is also a means to protect the safety of judges.
Later, it was found that every judge and lawyer who appeared in court needed to wear a wig to show a sense of respect and a strong sense of ceremony, because the law was solemn and needed its sense of ceremony.
And Hong Kong has obviously accepted this habit, where lawyers and judges will wear wigs in court. Because in the eyes of Hong Kong people, judges wearing wigs are more prestigious and professional judges.
Therefore, a judge without a wig is easily misunderstood as unprofessional or incompetent. This may also be a cultural difference.
After all, Hong Kong's legal system is independent and influenced by the British side. Of course, they also have their own ideas.
Now it has become a specific rule for Hong Kong to wear wigs in court. If one day you don't wear a wig in court, people will wonder if something is wrong.
Therefore, Hong Kong has been a British colony for too long, and some cultural influences have penetrated into Hong Kong, so the real origin may still be in the colonial period.
