"Black Night Cry", qin music. It was originally a folk song of Xiqu that expressed the theme of love in the Southern and Northern Dynasties. It was later lost, and now the commonly played "Wu Ye Cry" is played by the famous guqin master Yao Bingyan. To solve the problem, he quoted the composition of music by Linchuan King Liu Yiqing in the Book of Tang, Music, which was often used in later generations. There are words such as "feedback" and "struggle for the nest" in the score, indicating that the qin music describes the activities of Ciwu and the chicks. It should be noted that the crow here refers to the ciwu, that is, the jackdaw, not the crow.

The daughter of He Yan of the Later Han Dynasty heard the crows and thought it was an omen that her imprisoned father would be released, so she composed this song. However, there is another saying that is popular in the piano score: during the Southern and Northern Dynasties, the king of Song Linchuan, Liu Yiqing, was suspicious of the emperor, and he was worried that a catastrophe would be imminent, and he was very afraid. His concubine heard the crow cry at night and told her that she would be pardoned. Later, it was fulfilled, so I composed this song. The two different stories both reflect the feudal stratum's struggle and persecution, as well as their desire to be free, with Wu Yeti as a sign of a happy event. Therefore, there is a question that is explained as "Crying in the dark night, good things are near"
