Chinese era name A Chinese era name is the regnal year, reign period, or regnal title used when traditionally numbering years in an emperor's reign and naming certain Chinese rulers. Some emperors have several era names, one after another, where each beginning of a new era resets the numbering of the year back to year one or "yuán" (元). The numbering of the year increases on the first day of the Chinese calendar each year. The era name originated as a motto or slogan chosen by an emperor.
