Such Japanese translations are derived from the respective meaning of Chinese character, namely "Baku (縛)," which means capturing criminals, "sosei (雙世)," which means always suffering the consequences of pain and joy; "soo (雙王)," which means a king consisting of a paired brother and sister, and "byodo (平等)," which means the fair judgment of criminals.
“縛”は罪人を捕縛する意、“雙世”は彼が世中、常に苦楽の2つの報いを受ける意、“雙王”は兄妹一対で2人並びたる王の意、また“平等”は罪人を平等に裁くとの意から、これらの和訳がある。
