Gu (a.d.1613-1682) was a native of kunshan town, Jiangsu province, and people used to call him Mr. He took part in the anti-Qing uprising in the late Ming Dynasty. After his failure, he refused to cooperate with the rulers of the Qing Dynasty, and specialized in traveling around and conducting academic research. The following five-character ancient poem "Jingwei" expresses his patriotism:
Everything is unfair, so why bother?
An inch long, holding the wood forever.
I am willing to calm the East China Sea, but I will not change my mind.
There is no peace in the sea, and the heart is endless.
Oh! Have you noticed that there are many birds in the western hills?
Magpies come to swallows and make their own nests.
The first four sentences are about Jingwei Bird: There are many injustices in the world. Why do you want to fill the sea in vain? In the next four sentences, the poet said through the mouth of Jingwei that he was also a Jingwei who reclaimed land from the sea and died without complaint. The last two sentences satirize those who betray their country and seek glory with magpies and Yan, and laugh at them for forgetting national interests and only building their own comfort zone.
