There is a folk saying that "Grain Rain will see peony in the garden in three days" and "Peony will take the lead in peony pedicure", and there is also a proverb that "When the Chinese rose falls, only the pedicels will be removed, and bloom will not lag" to describe the spring scenery of the world. In folk proverbs, there is a sad legend: It is said that during the reign of Emperor Gaozong in the Tang Dynasty, there was a young man named Grain Rain who was very good at swimming. Once, his hometown of Cao Zhou was flooded. He used this skill to save the villagers, risked his life to save a peony flower and asked a gardener to plant it well. A few years later, Grain Rain's mother was seriously ill, and Grain Rain had to take care of her while doing things. At this time, a beautiful woman appeared in his family, taking care of his mother every day. Grain Rain and this woman have been in love for a long time. Just when Grain Rain wanted to marry this girl, she learned that this beautiful girl was the fairy peony, and it was the peony he saved several years ago. Fairy peony agreed to "stay until April 8 next year, and I will go to Gumen to settle down." Later, the vulture, the enemy of Peony Flower Fairy, became seriously ill, forcing Peony sisters to treat her illness and brew Huaruidan wine. The peony sisters refused to take their own blood and brewed Dan wine for the evil thief to drink, but they were taken away and detained by vultures. Grain Rain has experienced many difficulties and obstacles. On his birthday, he finally broke into the magic cave, defeated the vultures and rescued Hua Xian. When everyone was ready to go home, the vulture that was not dead stabbed Grain Rain with a dark sword. Sister Peony was so angry that she picked up Grain Rain's axe and chopped the dying vulture into a paste! Turned to help Grain Rain's body, sobbing. Grain Rain saved the lives of these flowers with his own life. From then on, on the day Grain Rain died, it would rain in the sky and all the peonies would bloom in memory of Grain Rain.

Grain Rain is the last solar term in spring. At this time, just after planting seedlings and planting new crops in the field, rain is most needed, so there is a saying that "spring rain is as expensive as oil". At this time, the eastern part of most parts of South China is abundant with rainfall of about 30 to 50 mm in late April of the year. The first heavy rain usually occurs during this period, which is beneficial to rice planting and the growth of corn and cotton at seedling stage. However, most of the rainfall in other parts of South China is less than 30 mm, so irrigation measures should be taken to alleviate the impact of drought. The mountainous areas in the northwest plateau are still in the dry season, and the precipitation is generally only 5 to 20 mm. The rainfall around Grain Rain in South China often "sneaks into the night with the wind, and moistens things silently" because the frequency of "late rain" is the highest in April and May. "It often rains at night and the river sill is clear", which is very suitable for crop growth and harvest.

Most weather proverbs of Grain Rain Festival revolve around the center of rain but no rain, such as "Grain Rain is gloomy, it rains in summer", "Grain Rain rains, and there is no dry soil for forty-five days" and so on.

There are also solar terms in Grain Rain, such as high temperature and frequent rainy days, which will cause the occurrence and prevalence of pests and diseases of wheat.
