Today, I have been looking at the picture below, especially the six words "Don't use the hidden dragon in the first 9th day of the year", which makes me dizzy.

The picture above is the Liuyao Qian hexagram (〉), which is composed of two threeyao Qian hexagrams (☰), so there are six yangyao .
We said in the previous article that the hexagram is a comprehensive description of the meaning of the hexagram. As shown in the above picture, the hexagram of the Qian hexagram is: Yuan, Heng, Li, Zhen.
The simplified line is more specific, which means explaining the meaning of each line in a targeted manner, or reminding us how to deal with people at different stages of development.
〔1〕What does the ninth day of the dynasty mean?
" Yijing " has only two basic elements: yang and yin, and the yang line is represented by the solid line "one", which represents the number as "nine"; Yin line is represented by the dotted line "--", which represents the number as "six" ( "Nine Yin Jing" and "Nine Yang Divine Arts" written by Jin Yong have nothing to do with this, which is the saying "Yang Jiu and Yin Jiu" from Taoist ).
hexagrams are sorted from bottom to top, and are the first, second, third, fourth, fifth and six lines, among which one line is "first" and the six lines are "up".
"Nine" means that the first line is the yang line.

〔2〕What does it mean to not use the hidden dragon?
The first line is at the lowest end of the Qian hexagram, just like a young man who has just entered the workplace and is still ignorant of the world. Based on this, learning to hide yourself like Qianlong without revealing your talents is the basic cultivation of dealing with people and the world. This is the enlightenment of Qianlong to us when dealing with us.
Among real historical figures, Zhuge Liang pushes the hidden dragon to the extreme, and hides in the cottage for 28 years before being discovered by Liu Bei .
There is a tough guy in " Meteor Butterfly Sword ", whose name is Yi Qianlong . In order to train the "Flying Tigers" for Sun Yubo , this guy has also been hiding for more than ten years. From this point of view, when Gu Long constructs the character Yi Qianlong, the inspiration should be from the Qianlong that comes from the "Book of Changes".
Although there is a hidden dragon, you should not use this trick, and it is basically not used. This is also Jin Yong's deliberate arrangement.

at the end:
"The Book of Changes" is really too difficult.
I learned six words today: "Ninth day of the lunar calendar - do not use the hidden dragon", which has made me exhausted.
What are the efficient learning methods for you? Can you share it?
