[Cf. Lao Tzŭ’s saying: "A violent wind does not last the space of a morning." (_Tao Te Ching_, chap. 23.) Mei Yao-ch’en and Wang Hsi say: "A day breeze dies down at nightfall, and a night breeze at daybreak. This is what happens as a general rule." The phenomenon observed may be correct enough, but how this sense is to be obtained is not apparent.]
