When she was young, Ling dared to laugh at Huang Chao's husband.
This poem was written by Song Jiang in Water Margin.
The meaning of this poem is: Although I served my sentence in Wudi (Jiangzhou), my heart is in Shandong (Liangshan). Wandering in rivers and lakes, I often lament the wasted years. If I realize my great ambition in the future, I can laugh at Huang Chao's behavior, because it is not done by a gentleman.
Note: Huang Chao was an anti-thief in the peasant uprising in the late Tang Dynasty.
