Piano, chess, calligraphy and painting are the first.

The function of piano, chess, calligraphy and painting is what the ancients said:

Yin and yang follow Qin evil;

Timing games with chess;

Distribute decrees in books;

Write a map with pictures;

As for where the source came from, it was found in an ancient book, and those who are interested can consult the numerous ancient books themselves. Qin, chess, calligraphy and painting are not trails like playthings getting tired and getting tired of entering the art, but are directly related to the roads and artifacts of building the country and governing the country.

Guqin, in particular, is the most crucial link for our country to get through and understand the black box structure of harmony between man and nature. If we don't study guqin and temperament, we can't understand the theory of Yin and Yang in Yijing, which is related to the six parts of Yijing, such as geomantic omen, algorithm, astronomy, traditional Chinese medicine, physiognomy and divination, among which the most profound one involves temperament and temperament. Therefore, if you don't understand guqin, you can't say "Yi", which is also called; Ancient "law, extremes, unification, calendar and qi" are all consistent things and are the core high-end resources of Chinese civilization; Based on the changes of the above seven strings and thirteen emblems, the qi of yin and yang is always the same; So the Twenty-four History of our country is gay, but not gay. Music is the outer layer of yin and yang, and law is the core; It is precisely because guqin has the function of explaining yin and yang that it is no exaggeration for the ancients to list guqin as the first of calligraphy and painting. It is also inevitable.

As for the guqin, the nylon strings are stretched evenly now, and there are few silk strings.

Guqin, especially a good piano, has a completely different effect from a nylon string; Using nylon strings is mainly due to the lack of rhyme, so it is difficult to pop up a strong, quaint and sad sense of history, and the harmony of silk strings is wonderful; Because many piano players now use overtone method to tune strings, each string of Guqin has no fine-tuning device like violin, so it is difficult to tune strings accurately according to pure tone, including the tunes played by Mr. Guan Pinghu and Mr. Cha Fuxi, and most strings are just accurate. Once completely aligned, the vibration of the seven strings of the Guqin itself can make the whole Guqin itself, including the platform, tremble slightly, and the wind in the piano room is thunderous. Therefore, Guqin adjusted the qi of heaven and earth according to the records in Huangdi Neijing, Lingshu Jing, Li Zhi of Han Shu and Li Zhi of Han Shu, so as to verify the 72-hour exchange of yin and yang, twelve qi and twenty-four solar terms with the qi of heaven and earth, and made adjustments in Tiansi Spring. Therefore, Guqin is better as a stringed instrument as far as possible.
