The answer to the question of whether there were monsters before the founding of the People's Republic of China is not very clear because monsters are usually described as supernatural existences. There are relatively few historical records and literary works before the founding of the People's Republic of China, mainly legends and myths. Therefore, there may not be enough historical records or literary works to confirm or deny the existence of demons before the founding of the People's Republic of China. In traditional Chinese culture, supernatural beings such as monsters and immortals had always been worshipped and portrayed as magical forces that could affect humans and the natural world. However, these descriptions were not necessarily true historical facts. They could also be fictional stories or myths. Therefore, whether there were demons before the founding of the People's Republic of China required specific analysis.
