Why did Wang Xizhi write Spring Festival couplets like "Happiness never comes twice, but it never rains but it pours"?

We all have the custom of posting Spring Festival couplets during the Spring Festival, mainly for good luck. This custom has existed since ancient times. In ancient times, many people would write their own Spring Festival couplets and stick them on their doorstep. One year, our great calligrapher Wang Xizhi posted a pair of Spring Festival couplets in front of his house. Someone stole it and posted another one, or someone else stole it. So he finally wrote a pair of Spring Festival couplets that didn't look so auspicious, and no one took them away. That is: happiness won't come twice, but it won't rain.

One year in the twelfth lunar month, Wang Xizhi's family moved to Shaoxing, Zhejiang, and the family was happy. At that time, the new year was coming, and Wang Xizhi was very happy, so he wrote a pair of couplets: spring breeze, spring rain, spring scenery, new year and new home. Wang Xizhi is very satisfied with this pair of Spring Festival couplets. He didn't expect that the Spring Festival couplets were stolen the next day.

The lost Spring Festival couplets could not be reported to the official, so I had to write a new pair of couplets and paste them: Qian Shan green in the north and Yan in the south. I went to see it the next day and it was stolen by someone else. Wang Xizhi saw that other people's families posted Spring Festival couplets, but only his own family didn't. So he wrote Spring Festival couplets, which never rains but pours, and posted them on his door. Now this Spring Festival couplets has not been stolen, because it looks unlucky at all.

In the early morning of New Year's Day, neighbors saw his family posting such an unlucky Spring Festival couplets and gathered at his door to talk about it. As soon as Wang Xizhi saw it, he went out and added a few words to the Spring Festival couplets: Happiness never comes in pairs, but it never rains but it pours. The artistic conception of the whole Spring Festival couplets has completely changed, and everyone admires Wang Xizhi.
