Answer:
Asia
Step-by-step explanation:
Ancient China was one of the oldest and longest-lasting civilizations in the history of the world. The history of Ancient China can be traced back over 4,000 years. Located on the eastern part of the continent of Asia, today China is the most populous country in the world. The Zhou dynasty was a Chinese dynasty that followed the Shang dynasty and preceded the Qin dynasty. The Zhou dynasty lasted longer than any other dynasty in Chinese history (790 years).
(So as it is on china then the continent would be on Asia).
