During the Spring and Autumn Period, Yu Boya was engaged in piano work, and his music vibrated greatly, which was difficult for ordinary people to understand. Only Zhong Ziqi can enjoy it. Drums and harps, aiming at the mountains, praised: "Good, I am like Mount Tai." Boyaxuan was full of water, and Zhong Ziqi sighed, "Good, like a river."

Later, Zhong Ziqi died, Boya lost his bosom friend, and he never played the piano again. Later generations used the metaphor of "high mountains and flowing water" to mean that the sound is hard to meet, and it also means that the music is wonderful.

2. Fall in love with this country

When Emperor Wu of the Han Dynasty, Li Yannian, a captain of Xielu, once wrote a song in front of Emperor Wu: "There are beautiful women in the north, and they are peerless and independent. Once you abandon this city, you abandon this country. I'd rather not know that the whole city has returned to China, and it's hard to find a beauty. " Liang Wudi sighed for a long time and said, "Is there such a person in the world?"

Princess Pingyang hinted that Li Yannian had a younger sister who was outstanding in appearance and graceful in dancing. Emperor Wu of the Han Dynasty called him to the harem, which was later the beloved Li Furen. The word "America laguna" is used to describe the beauty of women and is quoted a lot in literary works.

3. The second time

Xu Deyan, the son of Chen Daizi in the Southern Dynasties, married Princess Lechang, Chen Houzhu's sister. Afraid of the ruin of the country and the separation of husband and wife, they broke the bronze mirror into two halves, each holding half, and agreed to sell the mirror city on the fifteenth day of the first month of next year so as to meet each other.

After the destruction of Chen in the Sui Dynasty, the princess was acquired by the important officials of the Sui Dynasty and was extremely loved. When Xu Deyan moved to Beijing, he met a servant selling broken glasses in the street, which coincided with his seclusion. He wrote a poem: "the mirror goes with people, and the mirror returns to people." There is no shadow in the moon, and the moon is bright. "

When the princess saw this poem, she cried and didn't eat. Su Yang was very moved when she learned this, and finally reunited the couple. Later, people used "second reunion" to describe the reunion of husband and wife after separation.
