The Qing Dynasty, which lasted from 1644 to 1912, is often perceived as a period lacking in poetry and songs. This perception is primarily due to the suppression of intellectual and artistic expression by the Manchu rulers, who were initially unfamiliar with Chinese culture and literature. The Manchus, being a minority ethnic group, brought their own cultural practices and values to the throne, which often clashed with the established Chinese literary traditions.

One significant factor contributing to the lack of poetry and songs during the Qing Dynasty was the implementation of strict censorship and control over the arts. The Manchu rulers, particularly during the reign of Emperor Kangxi and Emperor Qianlong, enforced rigorous policies that suppressed dissent and discouraged creative expression. For instance, the "Selden Case" in 1696, where a British diplomat was accused of espionage and had his library of Chinese books seized, highlighted the government's suspicion of foreign influences and its desire to maintain control over intellectual activities.

Data from the "Selden Case" and other historical records indicate that the Qing Dynasty's censorship extended to the arts. The government banned or restricted the publication of certain books and literature, particularly those that were seen as critical of the regime or that contained elements of rebellion. This suppression had a chilling effect on poets and songwriters, who were wary of expressing their thoughts openly for fear of persecution.

Furthermore, the Manchu rulers' lack of familiarity with Chinese poetry and songs also played a role in the decline of these art forms. The Manchus, having their own traditional music and poetry, often preferred these forms over Chinese ones. This preference was reflected in the government's patronage and support, which favored Manchu arts and literature over Chinese traditions. As a result, Chinese poets and songwriters found it increasingly difficult to gain recognition and support from the ruling elite.

In conclusion, the Qing Dynasty's lack of poetry and songs can be attributed to the suppression of artistic expression by the Manchu rulers, the strict censorship policies implemented during the reign of Emperor Kangxi and Emperor Qianlong, and the preference for Manchu arts and literature over Chinese traditions. These factors combined to create an environment that was inhospitable to the flourishing of Chinese poetry and songs during the Qing Dynasty.
