Where can I find high-quality guqin？

The external features of a guqin include the body, surface, shaft, and string axis. The body of a guqin is the main part, which can be divided into three types: long body, short body, and small body, with the long body being the mainstream. The visible part on the piano surface has seven string tracks and thirteen badges. The shaft refers to the axle used for the strings, and buyers need to check if it is in good condition and if there is excessive wear. The chord axis refers to the mechanical part used for tuning and also needs to be checked for completeness.
Guqin can be divided into cedar and tung wood qin (Wutong, not Paulownia from Henan). These two materials are not necessarily good or bad, but due to the difficulty in finding old Chinese parasol wood, most of the so-called tung wood qin nowadays is replaced by paulownia. Paulownia has an extremely fast growth cycle, so although the wood is loose and treated, its unstable wood properties greatly reduce its collection value. The price of Laoshan Qin is relatively expensive, but its wood quality is stable, and its timbre can also play better, which has high practical and collectible value. The famous Tang Dynasty Lei Qin was made of cedar wood. According to the Record of Langyi (14), Lei Wei plays the qin, without having to use all the trees. When encountering a strong wind and snow, he goes to Emei alone to drink, wearing a straw hat, and enters the deep pine. He who listens to its continuous and melodious sound cuts it down, using it as a qin, which is better than the trees. The pine here refers to Emei pine, which is also known as the Emei fir. Most of the top quality of modern pianists are made of old cedar wood. Among the ancient qin styles that exist today, there are Fuxi, Lingji, Shennong, Lianzhu, Zhongni, Shikuang, Luoxia, Jiaoye, and other qin styles, among which the most common are Zhongni, Lianzhu, Fuxi, and so on. The names of Qin style are often derived from myths, historical allusions, or natural phenomena, and each name is a symbol.
How to choose a guqin: 1. It must be traditional. Yangzhou cedar (Yangzhou master has good craftsmanship), good craftsmanship is equal to good timbre. The guqin timbre will play better and better, and even if it doesn it start, it will not be good. The new guqin is very crisp, and it must be made of tung wood and chemical paint. Everyone must remember that this is a knowledge point. 2. Da Qi is mainly environmentally friendly and pure natural (Da Qi must not have a trace of flavor). Even a Da Qi is beautiful, and the appearance of the qin mainly depends on the master of Da Qi, which has nothing to do with the sound color. Anything too fancy is made by adding other materials, and Da Qi will oxidize and change during use, often changing with the player is mood. Therefore, do not start by checking whether the qin is fancy, as those are often not Da Qi craftsmanship, Like a large painted qin and jade, the soft light emanates from the inside out, not from chemical paint. Just like furniture paint, it emits thief light. Those who know how to appreciate the beauty of large paint. 3. For beginners, just listen to what you like. To have a stable voice, it is best to let the merchant choose. Of course, the tone will definitely vary depending on the price.
