A gross misunderstanding has been existing over a thousand years about a poem named Thoughts on a Still Night by Li Bai, in which the character Chuang means the rails round a well rather than a bed.

夜思誤解千百年，牀非臥具為井榦。

Moreover, even a child knows that frost forms outdoors, let alone Li the unique Banished Immortal.

霜結户外童且知，何言曠代一謫仙。
