Zhong Ruan is a medium pitch Plucking Instrument of the Ruan Family.
Ruan is a pucking instrument that has a long history. In BC 115, Han Wu Emperor wanted to make a plucking musical instrument immediately for the Wu Shun Princess whom he was going to marry. So he ordered his instrument technicians to make it in the shortest time possible. As a result, Ruan was invented. In Dong Jin (AD 317~420), Ruan Xian of "Zhu Ling Qi Xian" (The Talented Seven) can play this instrument well. And this instrument became popular among the people. However due to the chaotic situation at those times, the instrument was lost. It was not until Tang Dynasty (AD 684~701) that the Ruan was rediscovered and was named after Ruan Xian. In the modern China, Ruan is improvised upon and various sizes of Ruan are developed to give different tones and pitch.
