If "Guishan Cao" is the beginning of Confucius' travels around the world, then "Youlan Cao" records Confucius's summary of the various setbacks encountered in traveling around the world.

In the 14th year of Duke Ding of Lu (496 BC), Confucius led his disciples to leave the State of Lu and came to the State of Wei. Duke Ling of Wei began to respect Confucius very much, and gave Confucius 60,000 yuan according to the salary standard of the State of Lu, but he did not give him 60,000 yuan. What official position does he have, and he is not allowed to participate in political affairs. After about 10 months, Duke Ling of Wei listened to other people's slander, became suspicious of Confucius, and sent people to publicly monitor his actions. When Confucius saw this, he took his disciples to leave the state of Wei, intending to go to the state of Chen.

In the following years, Confucius could not stay in Wei State and left for the west. After passing Cao State, Cao Boyang did not meet him. When he arrived in Song State, Song Sima Huando hated Confucius and even threatened to harm Confucius. After living in Chen State for three years, he encountered In the chaos of the war, when they were planning to leave, the officials of Chen and Cai were afraid that Confucius would be reused in Chu, which would be unfavorable to them, so they sent laborers to besiege Confucius and his disciples in the middle of the road...

In his later years, Confucius led his disciples to travel around the world for 14 years, but he never met the Prince of Bole. Even when he was trapped in the two countries of Chen and Cai, and starved of food in the barren mountains and mountains, he still continued to sing. In his twilight years, Confucius still worked tirelessly to study the principles of the piano. On the way back to Lu in self-defense, I saw orchids and weeds growing together in the valley, just like a gentleman in a chaotic world. He was born at an untimely time, and he could not display his good character and talents. Play and sing "You Orchid Exercise".

Since ancient times, most of the literati have been born at an untimely, unappreciated talent, and have had many misfortunes, and Confucius is no exception. Confucius traveled around the world to teach his own ideas and moral concepts, but no country would reuse him. The orchid was originally the king of fragrant flowers, but now it is hidden in the valley. Confucius wrote "The Orchid", which is a sigh of the difficulty of the gentleman's way, and even more of the sigh of "natural talent is useless".

"You Lan Cao", also known as "Yi Lan Cao", was first said to be written by Confucius.

The qin song is like complaining, crying, resentment and anger. It expresses Confucius' inner world at this moment incisively and vividly, and entrusts all his thoughts and feelings on Lan. It is a beautiful Lan poem and a sad lyric. song. In the Tang Dynasty, "You Orchid Exercise" was very popular. Today, the earliest guqin score and the only written score "Jie Shi Diao · You Orchid" was handwritten by the Tang Dynasty. Bai Juyi also wrote the poem "Listen to You Orchid": " The ancient melody of the qin is Youlan, I am more attentive to see it. If you want to keep your body and mind at peace, you can’t play it as well as listen to others play it.” To express his true feelings.
