In 771 B.C., Hao, the capital of the Western Zhou Dynasty, was captured by Quan-Rong, a tribe of the Rong Nation. The Heaven-Son, Zhou You-King, was killed. The Capital Hao was destroyed. When many states supported Zhou Ping-King who was the heir of You-King to reoccupy Hao, they found it couldn’t be a capital again. So Zhou’s royal family had to move to the east, and chose Luo (Modern-day Luoyang) to be the new capital. Qin Xiang-Gong, the chief of Qin tribe escorted the Heaven-Son to move.
