A girl [plant] who has no sorrow, Wu Zhongshu calls it the antidote to sorrow. 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. The Book of Songs records that there was a woman in ancient times who planted day lilies in the North Hall of her home because of her husband's expedition to get rid of her troubles and forget her busyness. From then on, the world called her a "worry-free girl".

It's hard for others to know how much this woman can forget. But she loves daylily, which is really insightful. Among the cousins of Liliaceae, HEMEROCALLIS HEMEROCALLIS is not a noble family, but a "small family". Look at its shape, slender leaves, tubular flowers, each with 6 petals, spreading outward, and the color is orange-red. Generally, there are several flowers in each flower, which bloom from summer to autumn. Unfortunately, I opened the door in the morning and closed it at dusk, so I left in a hurry. According to flower connoisseurs, daylily, with its lush green leaves and Xiu Xiu flowers, exudes a graceful, dignified and elegant temperament, which makes people feel cordial and pleasing to the eye. No wonder the ancients compared it to the voice of a loving mother. 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, a nameless flower itself does not contain any elements to relieve troubles. It just helps people to shift their emotions while watching, relax for a while and forget their troubles for a while. 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 until I am old" to encourage her not to worry too much about family affairs. Looking at mortals who often eat earthly fireworks, I am afraid that few people can be completely carefree. Besides, there are many people with lofty ideals in the world who are often worried about the fate of the country and the sufferings of the people. It can be seen that you have been worried about what you should be worried about, and let it go and forget. Wu scholars call it "treating anxiety". Ji Kang's health theory says: "Hemerocallis forget their worries".
