Yin Tian Guqin, Zhang Guqin and Ni Guqin, compared with these three Guqin, generally Guqin must be after Zhang, and the remaining two are similar. But there is nothing wrong with Zhang for the 50 thousand and 100 thousand guqin, and the rest is that he will win. However, many people think that Ni's guqin is good, but people seldom hear about it. In the early years, it was not as good as Ni Guqin, but in the last three to five years, it has surpassed it.
Remember, whenever you choose an guqin, you should always look at it and listen to it. Don't always think about it.
