When was the earliest dice in China?

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. But in archaeology, the earliest dice appeared in Egypt. More than two thousand years ago, the dice in ancient Egypt were called Huangqi.
