Surnames come first: Fong or Tse or Au or Auyung.
Given names have two parts: a generation name (the same for each member of the same generation of a family) and a personal name, which comes last. People are known familiarly either by their nickname or by a diminutive formed by adding Ah- to the personal part of their given name. So, Kwan Suk Yin (surname Kwan) is known by her nickname, “Six Fingers,” or Ah-Yin (by her husband) or, later in life, Mrs. Kwan.
Cantonese and Mandarin (pinyin romanization)
We have used a Cantonese spelling for all names of people who spoke Cantonese to each other, and local places in South China. For national figures (for instance, Li Hongzhang) and names of provinces, we have used Mandarin pinyin romanization. The exception is the Chinese Revolutionary commonly known in the West as Sun Yat-sen (Mandarin pinyin: Sun Zhongshan).
