The Couplet of the Fourth Son-in-law Once upon a time, there was a fourth son-in-law who respected his father-in-law very much and often wrote couplets for him. One day, he wrote a couplet and posted it in his father-in-law's study: a will, there Success comes naturally The meaning of this couplet was that as long as one had ambition, one could overcome difficulties and finally succeed; as long as one worked hard, one could achieve one's goal. The father-in-law was very happy to see the couplet, thinking that he trusted and praised his son-in-law. So he often asked his fourth son-in-law to help him write couplets. As time passed, his reputation grew as his fourth son-in-law's couplets became better and better. One day, a guest came to his father-in-law's study and saw the couplet written by his fourth son-in-law. He could not help but sigh,"Your couplet is really well written. It not only expressed your ambition and determination, but also incorporated a profound philosophy of life." When the fourth son-in-law heard this, he smiled modestly and said,"Actually, I wrote this couplet for my father-in-law. I hope he can understand his goal and pursue it and work hard for it." Only by working hard can you realize your dreams." His father-in-law was very touched by this sentence. He deeply understood the intentions and talents of his fourth son-in-law. From then on, the couplet of the fourth son-in-law became even more deeply rooted in the hearts of the people and became a classic cultural landscape.
