At the end of the Southern Song Dynasty, Wen Tianxiang, who was the last Prime Minister of the Southern Song, was captured by the Yuan army in Guangdong. When the Yuan warship carrying him sailing down the Lingdingyang, he composed a poem titled "Crossing the Lingdingyang (Lonely Ocean)" to express his feeling:
I studied the classics diligently to become an official. Four bleak years have been spent in fierce battles.
Our land is broken like catkins in the wind. I wandered around like a duckweed soaked in the rain.
At the Shallows of Frightful, I fought my way at the frightful battle I couldn't won. On the Lonely Ocean, a lonely captured like me could only sigh.
Down the ages who could avoid his death? Let my loyal heart remain true and shine in the annals of history.
