Grain Rain is one of the 24 solar terms in China, which falls on around April 19th or 20th each year.

It represents the deepening of spring and is an important time for farmers to sow their crops. During Grain Rain, there is abundant rainfall, which is a crucial period for crop growth, hence its name "the rain for sowing grains".

Grain Rain is also considered an important symbol of traditional Chinese culture, representing the rich knowledge of solar terms, climate, agriculture, and human life in ancient China. In modern times, Grain Rain has been widely used in various cultural and business fields, becoming a source of naming for brands, products, and activities.

Drinking Grain Rain tea is a tradition during this solar term.

Grain Rain tea, also known as pre-rain tea or second spring tea, is made from tea leaves picked during this season, especially in the morning. The tea has a bright green color, soft leaves, and is rich in vitamins and amino acids with a pleasant aroma. It is said that drinking Grain Rain tea can clear heat, ward off evil, and improve eyesight. Therefore, on Grain Rain day, people will go to the tea mountains to pick some fresh tea and drink it.

Viewing peonies is another tradition during Grain Rain.

Peony flowers are called Grain Rain flowers or flowers of wealth and nobility, and viewing peonies during this solar term has been a popular entertainment activity for thousands of years.

In ancient times, there was also a custom known as "walking in Grain Rain". Young women would visit relatives and friends in their village, or go for a walk outdoors to merge themselves with nature and improve their physical fitness.

Grain Rain stickers are also widely used during this time. In order to reduce the damage of pests and diseases to crops and people as the temperature rises after Grain Rain, farmers would post Grain Rain stickers and pray for good luck while they enter the fields to eradicate pests.
