北宋初年有个大学士叫陶毂,他亲眼见过老百姓的住房是多么紧张。“四邻局塞,半空架版,叠垛箱笼,分寝儿女。”就是说房子太小,就在房子天花板和地板的中间加一层,隔成小复式。卧室太小,放不下床,就把箱子柜子什么的拼起来,让孩子们睡。 In the early years of the Northern Song Dynasty there was a bachelor named Tao He. He had personally witnessed how nervous the people's houses were. “Four o'clock concession, half-empty frame version, stack cages, sub-sleeping children.” That is to say the house is too small, in the middle of the house ceiling and floor plus a layer, separated into small duplex. Bedroom is too small, let go of bed, put the box cabinets what spell together, let the children sleep.
