Chinese
In either the traditional or modern age system, the word sui (traditional Chinese: 歲; simplified Chinese: 岁; pinyin: suì), meaning "years of age", is used for age counting. When a person's age is given in a publication, it is often specified whether that is his or her traditional age (traditional Chinese: 虛歲; simplified Chinese: 虚岁; pinyin: xūsuì) or modern age (traditional Chinese: 周歲; simplified Chinese: 周岁; pinyin: zhōusùi) or shisui (traditional Chinese: 實歲; simplified Chinese: 实岁; pinyin: shísùi).
