It never rains but it pours, which is an idiom in China. Pronunciation is fú wú shuāng zhì, huò bù dān xíng, which means that good luck will not keep coming, but disasters will follow.
From Shi Ming Nai 'an's "Water Margin" back to the 37th time: "After listening to this, Song Jiang decided that they would say," It's only bitter! Happiness doesn't come twice, but it doesn't rain alone. "
After listening to the conversation between two people, Song Jiang helped two workers and said, It's really hard for you. As the saying goes, good things will not follow, but disasters will follow.

In the Jin Dynasty, couplets were not perfect at that time, but they began to appear. Wang Xizhi, a great writer, often practices calligraphy on couplets, which is very natural and unrestrained. Because his calligraphy is so elegant, some people tear up the couplets he posted on the door, or take them home as treasures or sell them for money. At that time, Wang Xizhi had a headache.
Later, he thought of a way, so one day, he wrote a ***8-character couplet and posted it. Strangely, from that day on, no one coveted this 8-character couplet.
The simple four words in this couplet are "Happiness never comes in pairs", and the next couplet is also "Misfortunes never come alone". This is to warn them that if this couplet is torn off, it will be out of luck, because the first couplet tells you that happiness usually does not have two things at the same time, and misfortune usually does not have only one thing. Through the couplets outside, this meaning is implicitly revealed in pairs.
Later, this couplet was never torn off, so one day. Wang Xizhi asked the unknown calligrapher's son to add a few strokes before offering it. The warning of this couplet was replaced by an auspicious couplet.
The first part is changed to "Happiness has never come twice as fast as today", and the second part is changed to "It never rains but it pours last night", which means that although there won't be two happy events, you will have one happy event today, and there won't be only one disaster, but the disaster has passed last night. At that time, people admired not only the calligraphy talent of the Wangs and their sons, but also their superb literary level.
