# Tsui

Tsui is a surname. It is an alternative transcription of two Chinese surnames, namely Cuī (崔) and Xú (徐).

## Origins

Tsui may be an alternative transliteration of two separate Chinese surnames, listed below by their Hanyu Pinyin transliteration (which reflects the Mandarin pronunciation):
* Cuī (崔), which originated as a toponymic surname from a fief by that name in the state of Qi; a grandson of Jiang Ziya renounced his claim to the throne and went to live in that fief, and his descendants took its name as their surname. It is spelled Ts'ui$^4$ in the Wade–Giles system of transliterating Mandarin (which remains common in Taiwan and was used elsewhere until the mid-to-late 20th century). The spelling Tsui may also be based on the Cantonese pronunciation (Jyutping: Ceoi1; Cantonese Yale: Chēui).
* Xú (徐), which originated as a toponymic surname from the ancient state of Xu, adopted by the descendants of Boyi after the state was annexed by the state of Chu. The spelling Tsui is based on its Cantonese pronunciation (Jyutping: Ceoi4; Cantonese Yale: Chèuih); it is nearly homophonous with the above surname in Cantonese aside from the differing tone.

## Statistics

The 2010 United States Census found 3,168 people with the surname Tsui, making it the 10,180th-most-common name in the country. This represented an increase from 2,725 (10,748th-most-common) in the 2000 Census. In both censuses, more than nine-tenths of the bearers of the surname identified as Asian, and roughly two percent as White.
