What chinese territory continued its common law system

Answer: The Hong Kong Special Administrative Region

Explanation:

Common Law is an English unwritten law that originated in London. These are laws that are made by judges as they give verdicts on cases in opposition to laws made by the legislature.

They are mostly introduced from past cases and judgements and are not necessarily laid down laws.

While the Chinese legal system is under the jurisdiction of the People's Republic of China, the Hong Kong Special Administrative Region still continued the use of the Common Law system of government and its economic systems after being integrated into the Peoples Republic of China.
