The invention of Chinese writing character is generally estimated to be about 2500 to 2800 BC. Therefore, the people which settled in China, after the global dispersal following Tower of Babel account by God, must have know the many accounts of Man prior to the Babel dispersal. This would include the stories of the Creation by God, Fall of Man and Flood. It is natural for these people to put these pre-Babel stories (also recorded within Book of Genesis) into the development a writing.
From previous post: Genesis Stories Appearing in Chinese Writing
I found another good video by an individual to show a few of the many stories from Book of Genesis that have been found within the Chinese writing characters.
