The Celestial Empire was a name used to refer to China. It was a translation of Tianchao (Chinese: 天朝; pinyin: Tiāncháo), a name for China. Accordingly, the name "Celestial" was used to refer to Chinese emigrants to the United States, Canada, and Australia during the 19th century. Both terms were widely used in the English-language popular mass media of the day, but have fallen into disuse later on. Its usage has become popular again in the present day particularly among Chinese Internet users, referring to the current regime and implying the disapproval of its suppression and arrogance.
