Because Huang and Wang have similar pronunciations (Cantonese pronunciations are the same), they usually emphasize "big belly yellow", "grass head yellow" or "Jiangxia yellow" when explaining.

According to 1977, a paper on "surnames" published by China historians in Oriental Magazine, Huang is one of the top ten surnames of Chinese in the world.
