Historical source

dice

According to legend, the inventor of dice was Cao Zhi, a writer in the Three Kingdoms period. Originally used as a tool for divination, it later evolved into a game of concubines in the harem, betting on wine or silk sachets with dice points. At that time, the dots on the dice were all painted black, and it was not until the Tang Dynasty that red strokes were added.

However, according to textual research, the dice unearthed from Qi Tomb in Qingzhou, Shandong Province were not invented by Cao Zhi. Dice, as one of the six major operas in China, is regarded as the ancestor of China's operas, and it was popular as early as the late Spring and Autumn Period and the Warring States Period.
