May I ask the origin of the phrase "four famous works"

The origin of the term "Four Great Classics" can be traced back to the early 20th century. At that time, the Chinese cultural circle had their own views and evaluations on the development of Chinese classical novels. Among them, the "Four Great Masterpieces" became the most famous four works of Chinese classical novels and were also known as the classics in the history of Chinese novels. These four works were: Dream of the Red Chamber (1877): The Qing Dynasty described the love story of Jia Baoyu, Lin Daiyu and others, as well as the decline of feudal society and the complexity of human nature. 2. Journey to the West (1869): In the Ming Dynasty, the story of Sun Wukong and the others protecting the Tang Monk from the West depicted a magical world in myths and legends. 3 Water Margins (1898): The story of 108 uprising heroes in the Ming Dynasty reflects the darkness and corruption of feudal society. Romance of the Three Kingdoms (1899): The Yuan Dynasty tells the historical stories and heroes of the Three Kingdoms period, showing the political struggles and war scenes during the Three Kingdoms period. These four works had a wide impact on the cultural world at that time and were also regarded as classics in the history of Chinese novels. They had a high reputation and influence not only in China but also around the world, and they had become an important part of Chinese culture.
