Wuzhong scholars call it prevention of disease. Ji Kang's health theory says, "Hemerocallis forget their worries". (From Strange Tales) The day lily that people use to accompany their meals is scientifically called Hemerocallis. It has been planted for more than two thousand years, and it is a unique local product in China. According to the Book of Songs, there was a woman in ancient times who planted day lilies in the North Hall of her home because of her husband's expedition. From then on, the world called her a "worry-free girl".
Su Dongpo once blessed Japan: "Although the day lily is slightly open, it can extricate itself from loneliness and its heart is inserted in the graceful leaves." When he said "heart", he meant maternal love. Bai Juyi also wrote a poem: "Du Kang relieves boredom, and day lilies relieve worries." . He comforted Liu Yuxi, his confidant in his later years, for his life experience of repeated relegation. In fact, from a scientific point of view, an unnamed flower itself does not contain any elements to alleviate anxiety, but it helps people to shift their emotions, relax for a while and forget their worries for a while while while watching. In 1950s, it was reported that when beloved Comrade Dong was on a business trip in other places, he sent four sentences to his wife He Lianzhi: "I am smiling, and I will repay a girl who has no worries for her children, and I will laugh till I am old" to encourage her not to worry too much about family affairs.
