What's the difference between Hong Kong lawyers and mainland lawyers? How many kinds are there? Why do Hong Kong barristers wear wigs in court?

Hong Kong implements the British common law system, and lawyers are divided into litigators and solicitors.

In Hong Kong, litigators (also known as barristers) generally operate in the form of sole proprietorship and are responsible for their own profits and losses. However, in order to reduce expenses and make more effective use of resources, barristers usually set up offices in clusters to become law firms and share the expenses including the establishment of libraries.

Lawyers (also known as lawyers) generally operate in the name of law firms in the form of individual proprietorship or partnership, and most lawyers in Hong Kong are employed by law firms.

After Hong Kong's sovereignty was transferred to People's Republic of China (PRC), judges and barristers still wore wigs in the first instance of the High Court and the District Court.
