Leek is a plant with very high seasonal requirements. "Compendium of Materia Medica" records that "the first month is onion, and February is leek". The central idea is that the leek grown in February is the most suitable for human health, which can not only keep warm, but also enhance physical strength and promote blood circulation, which is completely in line with the regimen of "nourishing yang in spring and summer, nourishing yin in autumn and winter". Du Fu's poem "Spring is cut in the night rain" is a portrayal of this season. In early spring, children with low blood pressure and anemia who love to stay in bed every morning must seize this great opportunity. Women who often have cold hands and feet, backache and late menstruation are also suitable for eating more during this period.
