《旧唐书·本纪·卷十二》
至此赵赞又巧立抽盖房屋的税，由管辖的官吏拿笔计算，进入人们房中抄表计算，严刑峻法，愁苦哀叹之声，遍布天下。
至是又税屋，所由吏秉笔持算，入人庐舍而抄计，峻法绳之，愁叹之声，遍于天下。
Zhao Zan then created a new tax on the houses with roofs. The officials in charge took pens and entered people's houses to record the number of houses. They imposed strict laws and harsh punishments, and the cries of sorrow and lamentation filled the land.
