The long summer is late summer and early autumn. According to the theory of Yin-Yang and Five Elements, wood, fire, earth, gold and water correspond to liver, heart, spleen, lung and kidney respectively, so the spleen belongs to the earth, and the corresponding relationships between the five elements and seasons are spring and summer, long summer and autumn and winter. Soil corresponds to long summer, so long summer season is the best time to replenish spleen.
