What is the other shore flower? Is it from that book or an allusion?

The white flower on the other side is also called Man Dalavat, and the safflower on the other side is also called Manjusri Bodhisattva, which is one of the four flowers in Beijing. Originated in China's Yangtze River basin, distributed in the middle and lower reaches of the Yangtze River and parts of southwest China. Related records first appeared in the Tang Dynasty and were called "Wulitou Grass" and "Dragon Claw Flower". In China, the flowers on the other side are called golden lanterns, red arrows or meaningless grass. It was first seen in volume 19 of Youyang Miscellanies in the Tang Dynasty: "A golden lamp has nine shapes, and flowers and leaves don't meet. Vulgar and evil people planted it, and it is a meaningless grass. When parting, the roots are like taro sunflower, and there are twelve rings of wanderers. They are born, but they are not connected. And qi belong to each other, one alone shakes and the other leaves the mother. If the word is eaten by scholars, it is called a red arrow. " The flowers on the other side are also six flowers in Hokkekyo, which are four kinds of flowers from rain to rain. Hokkekyo prefaces: "The Buddha said that this sutra has passed, and he meditated and entered samadhi in infinite meaning, and his body and mind did not move. Lower Datura, Maha Datura (Datura is different from Datura), Manzhu Shahua, Maha Manshu Shahua, and Buddhism. " Translators are like two, translated into flowers, big flowers, red flowers and big flowers. Flowers of different colors and angles on the other side of the lamp house are French, which means sparse. The two words say, "Mahamanzhushahua is translated as' Great Red Tuanhua'." Hokkekyo asked: "Why does Manjushri's teacher shine in the rain? Datura, beads, sand, flowers and sandalwood are all pleasing to people, because all six kinds of vibrations in the world are sad and everyone is happy. Flower on the other shore is a Japanese translation of Golden Lantern. So in Japan, the flowers on the other side are also called "dead flowers", "hell flowers" and "ghost flowers". Flower of death
