origin
Yazheng, which has a long history, was originally an ancient and distinctive stringed instrument in China's east neighbor to Korea. It is the same as the oldest stringed instrument of the Han nationality in China, the zheng, which originated in Qin during the Spring and Autumn Period and the Warring States Period.

developing
Yazheng and Yazheng are two musical instruments with the same origin but different styles. As early as the Western Jin Dynasty more than 1,700 years ago, China had cultural exchanges with its east neighbor, North Korea. At that time, Korea consisted of Goguryeo (37 BC-AD 668), Baekje (18 AD-660 AD) and Silla (57 BC-AD 935).

With the frequent and in-depth cultural exchanges, the mutual influence has also increased day by day. In the Sui and Tang Dynasties, China has one of the seven pieces of music by Yang Jian, Emperor Wen of the Sui Dynasty, the nine pieces of music by Yang Guang of Emperor Yang of the Sui Dynasty, and the ten pieces of music by Li Shimin, Emperor Taizong of the Tang Dynasty. Galleria". The culture of Sui and Tang Dynasties, which was in its heyday in Chinese history, also deeply influenced the neighboring countries, and gradually formed three pieces of music in the three kingdoms of Korea, namely "Homeland Music", "Tang Music" and "Ya Music". Yazheng is a Korean stringed instrument created by the Korean people based on the zheng introduced from China.

After the 12th century AD, the Korean people first made the big zheng based on the ancient Chinese national playing the stringed instrument zheng, and then created the distinctive Korean stringed instrument ya zheng.

Written in the first year of Emperor Wenzong of the Li Dynasty (1451 AD), the article "Tang Le" in the official history of Korea written by Zheng Lingzhi and others, "The History of Goryeo, Lezhi" contains: "Tang Le Goryeo, the two are used in combination, so they are combined. Carrying his musical instruments: Fang Xiang (Tie 16), Dong Xiao (eight holes), flute (eight holes), (筚) Ji (nine holes), Pipa (four strings), Yazheng (seven strings), Dazheng (ten strings) Five strings), stick drums, Jiaofang drums, beats (six boards)."

In the early days, the yazheng was only used in "Tang Bu music", and in the middle of the 15th century AD, when Wenzong of the Li Dynasty, it was also used in "Xiang Bu music". Since then, the yazheng has been widely circulated among the Korean people, and it is a kind of stringed instrument that is very popular and loved by people.
