The image is a blackboard with white text written in Chinese. The text reads "The Stone Age has two phases historically, i.e., Old Stone Age and New Stone Age. In some places of Anyi, Leping, Pingxiang, and Xinyu of Jiangxi, human cultural relics in the Old Stone age, which are dated back to as early as 20 to 10 million years ago, have been found. Since Jiangxi is located in the junction of great rivers in the south and the north, the sites of the new Stone Age are widely scattered, and various primitive cultures are fully mixed. The cultures in here have not only their own characteristics, but also the cultural factors of the coastal area, Changjiang River and Huaihe River, as well as that in South China. Such colorful colors have well reflected the originality of the ancestors and the inclusion of the for-eigen advanced cultures."
