Tsui

Tsui may be an alternative transliteration of two separate Chinese surnames, listed below by their Hanyu Pinyin transliteration (which reflects the Mandarin pronunciation):[1][2]

• 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'ui⁴ in the Wade–Giles system of transliterating Mandarin (which remains common in Taiwan and was used until the 20th century in other regions).[3] 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.[4] 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.

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.[5]

• Hui (surname), the Cantonese spelling of another surname transcribed as Xǔ in Pinyin (許)
