Although the typical Chinese roof probably developed during the Shang (c. 1523-1027 B. C. ) or the Chou (1027-c. 256 B. C. ) period, its features are unknown to us until the Han dynasty.

尽管中国屋顶的建筑风格可能早在商代（公元前1523-1027年）或周代（1027-256），那一部分我们不知道直到汉代。

But we feel confident that the Shang period was the first true historical era, which was followed by the Chou dynasty, the longest dynasty in our history (from 1027 to 256 B. C.).

但是我们相信商朝是第一个真实的历史时代，随后跟著来的是周朝，它是我国历史上最长的朝代(从公元前1027年到256年)。
