Commemorate the solar terms in Cang Xie.

In memory of the solar terms in Grain Rain and Cang Xie.

"Spring rains shake the spring and clear the valley, full of midsummer, and summer and summer are connected." Grain Rain is the last solar term in spring, which means "Rain gives birth to hundreds of valleys", and it is also a good time for sowing and transplanting rice. The origin of this solar term is related to the creation of characters in Cangjie. Some folklore experts also said that Grain Rain is just a solar term, and there are not many customs around it, but more daily life.

Rain breeds hundreds of valleys and nourishes everything. In fact, the traditional 24 solar terms in China are closely related to farming activities, and Grain Rain is no exception. "Spring rain is as expensive as oil" means "rain gives birth to hundreds of valleys" in Grain Rain. At this time, the precipitation increased and the temperature rose rapidly. The seedlings in the field are newly planted, and some crops are newly sown, so they can thrive under the nourishment of rain.

As far as folk customs are concerned, Grain Rain customs also have a certain relationship with farming activities. According to folklore experts, Grain Rain is not a festival, so some customs around this solar term will appear more in "daily life", which is very local and not universal.

In ancient times, from winter solstice to summer solstice was usually divided into 24 initial solar terms, namely, winter solstice, slight cold, severe cold, beginning of spring, rain, fright, vernal equinox, Qingming, Grain Rain, long summer, xiaoman, Miscanthus, summer solstice, slight summer heat, great summer heat, beginning of autumn, summer heat, white dew, autumn equinox and cold dew.
