Kunqu Opera is one of the oldest forms of opera still existing in China, with its origins dating back to the end of the Yuan Dynasty (1271-1368). It has distinguished itself by the virtuosity of its rhythmic patterns and has exerted a dominant influence on all the more recent forms of opera in China, including the Sichuan and Beijing operas.
In 2001, UNESCO (United Nations Educational, Cultural and Scientific Organization) proclaimed Kunqu Opera as a masterpiece of the Oral and Intangible Heritage of Humanity (a UNESCO program that ensures the best of every country's traditions is preserved and developed as well as made known to the outside world).
