後三国時代
The same term is pronounced "manse" () in Korean. In Silla, it was used as a casual exclamation. It was a part of the era name of Taebong, one of the Later Three Kingdoms declared by the king Gung Ye in 911. During Joseon, Koreans used "cheonse" (, "one thousand years") in deference to the Chinese emperor's ten thousand years.
