The name "汪东城" is formed as a three-character sequence where "汪" serves as the surname, composed of the water radical (氵) and the component "王", while "东城" constitutes the given name, with "东" being a character meaning "east" and "城" meaning "city", itself formed by the earth radical (土) combined with the component "成". The name is constructed by juxtaposing these individual characters, each with its own structural composition and literal meaning, into a conventional personal identifier.
