嗯，我见过。和你有一样的感觉。不过四合院的起源比石库门早很多。我看书上说，四合院元朝就有了。它之所以叫四合院，是因为房屋是由东西南北四面包围，呈口字形， 中间是花园。大片的四合院中间的通道叫胡同。唉，你知道石库门的起源吗？

Yes, I’ve seen those. I agree with you. Siheyuan have a much older origin than shikumen. According to a book that I read, they date back to the Yuan Dynasty. They got their name because the rooms are surrounded on four sides by walls, forming a square shape. The garden is in the center. The lanes running through blocks of siheyuan are called hutong. Do you know the origin of shikumen?
