The idiom "夏雨雨人" (xià yǔ yǔ rén) originates from the Western Han Dynasty book "Shuo Yuan" by Liu Xiang, which discusses ethics and governance. In the chapter "Gui De," the importance of virtue is highlighted through various examples.

One anecdote features Guan Zhong, a famous statesman, reflecting on his own influence. He encounters Meng Jianzi, a former prime minister who, after falling from grace, had only three loyal followers remaining from thousands of former retainers.

Meng Jianzi explained that these three were people whose parents he had helped to bury or whose family members he had saved from legal troubles.

Hearing this, Guan Zhong sighed and lamented, "Alas! I will surely decline. I cannot be like the spring breeze blowing upon people, nor can I be like the summer rain falling on people. I will surely decline."

Guan Zhong's words convey his regret that he had not provided timely and genuine help to others, unlike Meng Jianzi, whose actions were as comforting and beneficial as a refreshing summer rain.
