Quick Facts
Origin and History of the Cai Family Name
The origins of the Cai surname can be traced back over 3,000 years to the Western Zhou Dynasty. It began with Ji Du, the fifth son of King Wen of Zhou. Following the establishment of the Zhou Dynasty, King Wu granted his brother Ji Du the fief of Cai, located in present-day Shangcai, Henan Province. Ji Du became known as Cai Shu Du. Although the state faced political instability during the 'Rebellion of the Three Guards,' the lineage was preserved through his son, Ji Hu, who was recognized for his virtue and reinstated as the ruler of Cai. The State of Cai survived for several centuries through various relocations until it was eventually annexed by the State of Chu in 447 BC. Following the state's fall, the descendants of the ruling house adopted 'Cai' as their surname to honor their ancestral land.
What Does the Chinese Surname Cai Mean?

In the context of the imperial court, the term was also associated with a large, sacred turtle used for plastromancy, symbolizing immense wisdom, divine connection, and longevity. Over time, the character evolved from its botanical and ritualistic origins to become a habitational name.
