Zou (state)
Zou (), originally Zhu () or Zhulou (), was a minor state that existed during the Zhou dynasty of ancient China. History. King Wu of Zhou granted Cao Xie (曹挾), an alleged descendant of the Yellow Emperor through his grandson, the legendary emperor Zhuanxu, control of the small state of Zhu as a vassal ruler under the State of Lu with the feudal title Viscount (子), but later holding the title Duke of Zhu (邾公). The ancestral surname of the ruling family was Cao (曹). Zhu subsequently changed its name to Zou. The state of Zou was located in the southwest  of modern-day Shandong Province. Its territory is now the county-level city of Zoucheng. Demise. Zou was conquered and annexed by the state of Chu during the reign of King Xuan of Chu (r. 369–340 BC). The people of Zou and their descendants adopted the Zhu (朱) or Zou as their surnames. Legacy. Zhu (朱), without the radical, is one of the most common surnames of modern-day China. Another, albeit less common surname Zou (鄒/邹) is also derived from the former name of the state. The noted Neo-Confucian Zhu Xi descends from the ruling house. The  small state of Zou, however, is most famous as the birthplace of the Chinese philosopher Mencius. As the overlord State of Lu was the home state of Confucius and many of his disciples, this means that Confucianism's founder, and most of its minor sages and wise men hailed from or had ancestral roots in these two ancient states of China.
