Chinese 伍: from the name of Wu Can, an official of the state of Chu during the Spring and Autumn period (722–481 BC). At one time, the states of Chu and Jin were at war. The general of Chu viewed the strong position of the Jin and recommended retreat. However, a minor official, Wu Can, performed an analysis of the situation which concluded that an attack would be better. The prince of Chu agreed with Wu Can, which resulted in a victory over the Jin. Wu Can then became a senior official and used part of his given name, Wu, as his new surname.

Chinese 巫: from the name of Wu Peng, doctor of the legendary emperor Huang Di (2697–2595 BC).
