Family Name: The surname 毕 (Bì) originates from the Zhou Dynasty (1046–256 BCE) and is derived from the Ji family lineage. It traces back to Duke Gao of Bi, the 15th son of King Wen of Zhou, who was granted the fiefdom of Bi (modern-day Xianyang, Shaanxi). His descendants adopted the surname 毕 as a tribute to their ancestral land.
