With the continuous development of modern agriculture, the 24 solar terms have been given new meanings in different regions. Some agricultural proverbs in the south of China, such as "Small Man, plows and harrows hang high", "Small Man is dissatisfied, so dry up the ridge", and Xiao Man uses "full" to describe the rain. Xiaoman is the season for transplanting rice. At this time, if there is not enough water in the field, the ridge may crack. The "fullness" here is enough to explain farmers' expectations for rain.

Xiaoman is the second solar term in summer. On May 20-22 of the solar calendar every year, it means that the seeds of summer crops are full and not yet mature, but small and not yet full; This solar term means entering the rainy season of precipitation, which reflects the climatic characteristics of heavy rainfall: "Small full and small full, rivers are gradually full".

The sun reaches longitude 60, declination+20 09', Pluto closes the moon, Pluto is 2.86 degrees north of the moon, and Mercury closes the sun, so it is invisible between the sun and the earth.
