The Dragon King's Night Vision

A minister working for Emperor Town Tae Zung was going to be executed. The Dragon King begged the Emperor to save him, so he agreed and set an execution time of 1145 on a certain day. But while playing chess with the minister, the Emperor blurted out: Is it 1145 yet? And then took a break and fell asleep. He did not have time to kill the Dragon King in person. So he killed him in sleep. A door god is there to protect homes and palaces against evil, day and night.
