Extended data:
It is said that in order to find Mr Right, Su Xiaomei used literary works to choose her husband. As soon as the news came out, there were countless suitors. One of them is a rich boy named Fang, who has admired his little sister for a long time. After hearing the news, he quickly made a choice. He presented many proud poems, but when my little sister saw them, they were as light as white water, so she picked up a pen and approved a pair of couplets on it: the pen is short of talent, but she has no idea. ?
Su Dongpo was worried when he saw the couplets of Miss Sister. In order to avoid right and wrong, I quietly added a sentence to my sister's couplet and changed it to: a little talent at the bottom of the pen has infinite strategies in my heart. Fang was ecstatic after reading it. He is eager to meet Su Xiaomei to express his heart.
