1. According to the Book of Changes, judging from the eight diagrams in the Book of Changes, the southeast is the direction of Xun. The hexagram "Xun" symbolizes "wind" and the five elements belong to "wood". The fifty-seventh of the sixty-four hexagrams "Xun" is the same hexagram. Xun is the wind, and the two winds are the most important, which means smooth but not reverse, symbolic and popular. Therefore, the peacock's "flying southeast" means flying with the wind, flying long with the wind, and flying southeast without going against the wind.

2. Peacock flies southeast: In the story of peacock flying southeast, the marriage tragedy between Jiao and Liu occurred in Xiaoligang, Huaining County. Xiaoli Port, a small city port, is located 20 kilometers north of Huaining County, bordering Qianshan County. Jiaojia is located in Jiaojiaban (now Qianshan County) on the other side of Xiaoshigang River, and Liu Jia is half a mile east of Xiaoshigang. Geographically, Liu Jia is located in the southeast of Jiaojia. Because his hometown is in the southeast, and Liu's corpse is also by the Xiaoshigang River in the southeast, Jiao Chuqing died facing the southeast. Peacock Flying Southeast expresses the desolation of this love tragedy.

3. It comes from Lu Kanru's statement when he defended his doctoral thesis at the University of Paris: When Lu Kanru defended his doctoral thesis at 1935, the examiner asked a strange question: "Why didn't the first sentence of the poem" Peacock flies southeast "say" Peacock flies southeast "? Lu Kanru replied: "Because there are tall buildings in the northwest. Lu Kan responded tactfully by quoting the sentence "There are tall buildings in the northwest and clouds on the horizon". However, there are still many scholars who study this reason rigorously. One of them is a metaphor of death.
