What does it mean to eat beans in the long summer?

Broad beans and amaranth are two of the "long summer and three fresh". After broad beans are soaked and germinated in water, they are also called "germinated beans", so eating broad beans is a "fat" color head; And after eating amaranth, there is still red soup in the bowl, which is a good color of "red (flood)".

Chang Xia said that saying goodbye to spring is the beginning of summer. Spring comes and summer grows, autumn harvests and winter storage, and in the long summer, everything is thriving. Because China has a vast territory and a large span from north to south, natural rhythms vary from place to place. In the long summer season, only the area south of Fuzhou-Nanling line in China enters the real summer of "the trees grow dark in summer and the balcony reflects into the pond"; And parts of the northeast and northwest just have the breath of spring at this time. According to the classification standard of modern climatology (climate average temperature) in China, the daily average temperature in long summer has risen steadily to above 22℃.
