Minor snow is the second winter solar term of the year. The solar terms were defined based on the weathers around the yellow river area, this weather does not apply to Taiwan. In the yellow river area, after the minor snow, temperature gradually becomes even colder till it begins to rain. Beginning to snow, the quantity isn't much, thus it's name minor snow.
In Taiwan the more obvious change is the winds. Winds become stronger due to the north eastern winds. There will no longer be thunder and pouring rains. If there is still thunder, this means there are abnormalities in the weather.
「月內若陳雷，豬牛飼不肥」If the month starts and there is winter thunder, the animals will not grow well.
The Chan Master mentioned the solar terms is a good time to meditate! Try and see for yourself if there is any difference!
