The incense hall is located in the center of the Pentagon, Wuzhigou Park. It is a completely wooden building. It needs to take off its shoes and go inside. The Museum of Philosophy was the name of the Museum of Correspondence in the period of the Shogunate. It was the northern stronghold of the Shogunate to carry out official duties within the five outlines. In 1871, all the buildings in the Five Barriers were destroyed during the Boxer Wars. What we see now is that the Boxer House was built later. So this building feels too new and has no sense of history. It is only the central building of Wuziguo Park and has its important position.
