Guard Room Introduction: The Guard Room is located at the entrance of the palace, where the guards responsible for palace security live. There is a ceramic heating stove on the right side of the door. Like all the heating stoves in the palace, it has no openings. Instead, it supplies heat to the room through the heating channel from outside the palace. This does not affect the daily life of the royal members, but also maintains the indoor atmosphere. For sanitation, this facility was used until 1992 when it was cancelled.
