This interesting postcard shows the food associated with the time of the year.
Now I hope to get the other 23 cards associated with the 24 solar terms (ha ha).
*****
The 24 solar terms, based on the sun's position in the zodiac, were created by farmers in ancient China to guide the agricultural affairs and farming activities. The 24 solar terms reflect the changes in climate, natural phenomena, agricultural production, and other aspects of human life, including clothing, food, housing, and transportation. The 24 solar terms play important roles and have greatly influenced people's basic needs in life, and they still have an important function nowadays.
The 24 solar terms are:
Start of Spring lì chūn 立春
Rain Water yǔ shuǐ 雨水
Awakening of Insects jīng zhé 惊蛰
Vernal Equinox chūn fēn 春分
Clear and Bright qīng míng 清明

The solar terms known as Start of Spring, Start of Summer, Start of Autumn, and Start of Winter are used to reflect the change of seasons, dividing the year into four seasons of exactly three months. While this fits an ideal pattern of dates, it does not reflect observable reality in most of China.
The solar terms of Vernal Equinox, Autumnal Equinox, Summer Solstice and Winter Solstice are divided from an astronomical aspect, reflecting the turning point of the variation of the altitude of the sun.
Minor Heat, Major Heat, Limit of Heat, Minor Cold, and Major Cold reflect the changes of temperature in different periods.
Clear and Bright, Rain Water, Grain Rain, Minor Snow, and Major Snow, White Dew, Cold Dew, and Frost Descent reflect the phenomenon of precipitation, indicating the time and intensity of rainfall, snowfall, dew, and frost.
Small Full (Grain) and Grain in Ear reflect the maturity and harvest time of crops, while Awakening of Insects reflects observed insect activity.
