The lonely phoenix tree "the moon is like a hook, and the lonely phoenix tree locks the autumn in the deep courtyard." These two sentences describe the scenery and the desolate environment in which the late Lord lived. He boarded the west wing, looked up and saw the crescent moon as a hook, hooking up a string of old grievances and new worries; Overlooking the shade of tung, the courtyard is locked in clear autumn. In the bleak scenery, there is deep sorrow and hatred, and there is affection and overflow in the scene. Chinese parasol tree, in classical poetry, has always been a sad image, "Chinese parasol tree, it rains in the middle of the night, and it is more bitter to leave love" (Wen "More Leaky"), "I miss you according to my promise, and the leaves of Chinese parasol tree are cool at night" (Liu Fuzhi's "Qingpingle") and "Chinese parasol tree has only one leaf, but I don't know how many autumn sounds" (Zhang Yan's "Qingpingle" is an autumn tree. "Where sorrow is synthesized, autumn leaves keep people's hearts" (Wu Wenying's Tang Duoling), autumn scenery aroused a sad mood. Most people will feel cold and lonely in such a deep courtyard with phoenix trees locked in autumn, not to mention Li Houzhu imprisoned by the monarch. In the past, he was a monarch, living in "Long Ta in Fengge was alone, and the branches of Yushu were smoke" ("Broken Array"), accompanied by "Filing moths in the Spring Palace" ("Jade House Spring"). The place where he lives now is "Lonely Wu Tong Shen Yuan", accompanied by "the moon is like a hook". How long should his inner sadness be!
