What's the difference between guqin and guzheng?

Guzheng consists of a panel, a wild goose column, strings, a front Yueshan, a string nail, a tuning box, a foot, a back Yueshan, a side plate, a sound outlet, a bottom plate and a string piercing hole. The shape of the Zheng is rectangular, and the wooden sound box and the Zheng column (that is, the Wild Goose Pagoda) can move freely. One string, one tone, five tones. There were thirteen strings in the Tang and Song Dynasties, and then increased to sixteen, eighteen, twenty-one and twenty-five strings. The most commonly used specification at present is 2 1 string. The model of guzheng is usually represented by S 163-2 1, S stands for the S-shaped moon mountain, which was invented by Zheng Fuxiu, 163 stands for the length of guzheng 163 cm, and 2 1 stands for the number of strings of guzheng 2 1. Guqin, also known as lyre, Qin Yu and lyre, is one of the oldest plucked instruments in China. It is generally about three feet six inches five (about 120- 125 cm) long, symbolizing 365 days a year (365 degrees on Sunday), about six inches wide (about 20 cm) and about two inches thick. The lower part of the piano body is flat and the upper part is curved and convex, symbolizing heaven and earth respectively. The overall shape is made according to the shape of the phoenix, and its whole body corresponds to the phoenix (or human body), including head, neck, shoulders, waist, tail and feet.

Guzheng is an ancient national musical instrument, which prevailed in Qin area during the Warring States Period. The materials quoted in Sima Qian's Historical Records and Biography of Lisi are quite noteworthy. A passage about the music and dance of the State of Qin in Li Si's Book of Persuasion: "It's really Qin Zhisheng who hits the urn, knocks the bow and plays the piano to fight. Those who write about Zheng, Wei, Sang Jian and Wu Xiang are also happy in foreign countries. Today, I won't knock on the urn, I'll take Zheng and Wei, and I won't play Zheng. What if it is? I am very satisfied with the present, but I am just very comfortable. "

On the other hand, guqin was a popular musical instrument in Confucius' period. It has been circulated in the history of China for more than 3,000 years without interruption, and it still echoes in the study and on the stage. In the long history of ancient China society, "Qinqi Calligraphy and Painting" has always been regarded as the only way for literati to cultivate their self-cultivation. Guqin, because of its clear, harmonious, light and elegant musical character, ranks first in Chyi Chin's calligraphy and painting, which is in line with Feng Ling's arrogant and otherworldly mentality.
