What does it mean to grow a line a day after eating the vernal equinox?

There is a proverb about diet in the solar terms of the vernal equinox: after eating the vernal equinox meal, you should arrange a line every day. After the vernal equinox, human metabolism is vigorous, blood circulation is accelerated, respiratory and digestive functions are strengthened, and endocrine hormones, especially growth hormones, are secreted. Children in the growth and development period are the best time to grow up.

The World Health Organization survey also found that the growth rate of children and adolescents is different in four seasons. Children grow faster in spring and summer, the fastest in spring, and the height growth rate is 2-2.5 times that in autumn.

Growing up is inseparable from vitamin D. There are many kinds of spring equinox rice, and mushroom rice is a common one. Because mushrooms are rich in vitamin D, dried mushrooms contain more minerals such as calcium, phosphorus and iron. The iron content is more than 8 times higher than that of spinach, and the zinc content is more than 3 times that of milk powder and soybean.
