Introduction to "Mountain Rain": In 1933, Wang Tongzhao's novel "Mountain Rain" came out. This masterpiece, which marked the new development of realism, shocked society once it was published. The gloomy novel describes the reality of the rapid economic collapse of northern rural areas under the pressure of imperialism, feudal forces, and warlords, and reflects the awakening of farmers. Because his work exposed the darkness of society, it was banned by the authorities the following year. Wang Tongzhao himself was forced to leave Shanghai and study in Europe at his own expense.
