From Fan Zhongyan's "Mr. Yan's Ancestral Temple", "Yunshan is grey, the rivers and seas are boundless, the gentleman's wind is long, and the mountains and waters are flowing", which means: the misty hills are gloomy, the rivers and rivers are boundless, and Mr. Yan's moral character is higher than the mountains and longer than the Yangtze River. Although it can't reach such a height, it is very desirable.
