This instrument is like zhongruan, but it isn't. It has only three strings, just like Qin Yue, only three strings. What kind of musical instrument is this? One of the strings in this painting is broken. Yueqin is a traditional plucked instrument in China, which originated in the Han Dynasty. The speaker is full of circles and the neck is short. The total length is 62, and the speaker diameter is 36.3cm.. The borders of the neck and speaker are mahogany and rosewood, and the borders are six boards of the same specification. The front panel and the back panel are made of paulownia wood. There are two sound beams and two sound columns in the box. Four axes, four strings, every two strings are homophonic, and the five degrees are fixed. There are eight or nine grades on the neck and panel.

With the passage of time, Qin Yue is constantly changing and developing. For example, after Qin Yue was introduced into Taiwan Province Province, its shape changed a little. Yueqin in Taiwan Province Province has a long neck and a round wooden speaker, occasionally hexagonal or octagonal. Silk thread was used in the early days, but now nylon thread is commonly used, and fishing line is also quite popular. It's Taiwan Province Taiwanese Opera and Taiwanese Opera. Taiwan Province Yueqin is also used for the rap of Taiwan Province Gezi Opera (Mi Opera) and Gezi (known locally as Jinge, the floorboard of folk songs).

Hope to adopt, thank you.
