Introduction to the Bathhouse: The Bathhouse is a place where candidates take a bath before the exam and change into exam clothes after bathing. This is intended to prevent candidates from carrying relevant materials, books or writing relevant answers on their arms or bodies into the examination room to cheat. Located in a long and narrow section to the west of the West Official Hall, there are ten arched rooms in a row, with water flowing on the north and south sides, and the door facing south. It is 29.8 meters wide from east to west and 6.5 meters long from north to south. The west end room is a well room with an ancient well inside.
