Zhu is the pinyin romanization of five Chinese surnames: 朱, 祝, 竺, 猪 and 諸.
It is alternatively spelled Chu (primarily in Hong Kong, Macau and Taiwan), Gee[citation needed][clarification needed] in the United States & Canada, and Choo (mostly in Singapore and Malaysia).
The ancestral surname (姓) of the ruling family of the State of Zhu (邾) was Cao.
During the Ming dynasty, some people of the Zhu clan moved to Taiwan, and others later migrated to Southeast Asia, Europe and the Americas.
[4] A 2013 study found that it was the 14th most common surnames, shared by 17,000,000 people or 1.280% of the population, with the province with the most being Jiangsu.
