The entrance to the yamen faces south, so it is reasonable to have no money. How did this sentence come down?

In ancient China, the buildings of the imperial palace and yamen all face south, which is called "facing south and facing north". The main entrance faces south, so the entrance of yamen faces south.

As for saying that "you can't get in without money", it means that officials are corrupt and take bribes and don't avenge the people! !

Now, the gates of Nankai District Government, Municipal Procuratorate, Municipal Fire Bureau and Municipal Intermediate People's Court along huanghe road and Nanma Road also face south.
