Xin dynasty
Most Chinese era names consisted of two Chinese characters, even though era names with three, four and six characters also existed. "Shijianguo" (; lit. "the beginning of establishing a country") of the Xin dynasty, "Tiancewansui" (; lit. "Heaven-conferred longevity") of the Wu Zhou, and "Tiancilishengguoqing" (; lit. "Heaven-bestowed ritualistic richness, nationally celebrated") of the Western Xia are examples of Chinese era names that bore more than two characters.
