《管子·四时》
它的德性表现为和平而均匀，中正而无私，实实在在辅助着四时：春天生育，夏天长养，秋天聚集收成，冬天积储闭藏。
其德和平用均，中正无私，实辅四时：春嬴育，夏养长。秋聚收，冬闭藏。
Its virtue is to be tranquil and even, impartial and selfless, and to assist the four seasons comprehensively: birth in spring, growth in summer, harvest in autumn, and storage and hibernation in winter.
