The story background of Water Margin is Song Dynasty. At that time, it was a fashion for men to wear flowers, and it was also a symbol of the status and rank of the upper class. Moreover, Song people thought that wearing flowers would be rich and glorious.

There are allusions to "four-phase praise"

In ancient times, Yangzhou peony was very famous, and it was also called Luoyang peony in the world. According to legend, during Han Qi's tenure in Yangzhou, there was a peony in the back garden of his official office, which was divided into four branches, each with a flower. The colors of these four flowers are very special. The petals are red from top to bottom, but there is a yellow nucleus in the middle, which looks like an official of the Song Dynasty wearing a red robe and a golden belt around his waist. Therefore, people at that time called this peony "golden waist" or "golden belt". The occasional "golden belt circumference" is the result of variety variation, which is very rare. According to folklore, once Yangzhou is surrounded by a golden belt, there will be a prime minister in the city.

Han Qi thought it was a rare opportunity, and opened a "Golden Belt Surrounding" in the garden, and wanted to invite three guests to watch it together, to show that the four flowers were celebrating together. At that time, Wang Jue and Wang Anshi were both in Yangzhou City, so Han Qi invited them to your home. But at this time, one person is still missing. What shall we do? Han Qi temporarily found a passing courtier, Chen Shengzhi, to make up the numbers. The four men were drinking and writing poems under the flowers. They also took off four "golden ribbons" and put them on their heads.

Incredibly, in the next 30 years, Han Qi, Wang Jue, Wang Anshi and Chen Shengzhi all became prime ministers of the Song Dynasty, and the story of "praising the four phases" spread from then on.
