Meaning: The compound surname 第五 ('Dì Wǔ') originates from the Han Dynasty (206 BCE–220 CE). It traces back to the powerful Tian clan of the Qi state during the Spring and Autumn period. When Emperor Gaozu of Han established the Han Dynasty, he divided the Tian clan into eight branches and bestowed surnames from 第一 ('Dì Yī', meaning 'First') to 第八 ('Dì Bā', meaning 'Eighth') to weaken their influence. The 第五 branch became the 第五 surname.
The surname 第五 is a unique ancient Chinese surname, originating from the Han Dynasty as one of eight divisions of the powerful Tian clan, symbolizing the 'Fifth' branch.
