After Long 'en Temple, it is Crescent City. Then why is it called Crescent City? Because "people have joys and sorrows, and the moon is full of rain and shine", the full moon symbolizes reunion and the crescent moon represents dispersion. Death is a loss, so the tower was built in a crescent shape to show sadness. Between Fangcheng and Baoding in the imperial tomb. To the north of the courtyard is Crescent City, which is actually a wall. Stick a shadow wall in the middle of the new moon city.

Crescent city is also known as the dumb courtyard in official history. It doesn't seem strange, but it's actually a key place. Because the glazed screen wall in the courtyard just blocked the entrance to the underground palace, the Shinto in the courtyard was just below the inclined pyramid-shaped mound that entered the underground palace, and the coffin of the former emperor was sent to the underground palace from here.

Architectural records

Legend has it that in order to keep the secret of the entrance to the underground palace, all craftsmen used in the Crescent City project must be mute, rest during the day, work at night, be blindfolded on the way to and from work, and be sent to remote areas with few people after completion. Because this courtyard was built by dumb people, it is called "dumb courtyard".

Such a legend is not credible, because although the dumb can't speak, they can still write, draw and gesture, and it is still possible to reveal the secret. Relevant experts and scholars looked through various books and found the origin of the name "Dumb House" from architectural books.

It turns out that in ancient buildings in China, those parts or components that are hidden and invisible from the outside are usually named after the word "dumb", such as "dumb pawn" and "dumb rafter", which is why there is such a strange name as "dumb courtyard".
