What are the reasons for the tragedy of love in "Poetry - Wei Feng - Rogue"?

① The hero's change of heart and violent character, as well as the oppression of women by the husband's power.

In a patriarchal society, women are in a subordinate position economically and politically, and their life is so small that they rely on their husbands for their happiness. If she meets a husband who is irresponsible for her feelings and family, her tragedy is inevitable.

②Social reasons: reflecting the prevailing contradiction between love and propriety.

The love between the heroine and the hero began at first sight in the bazaar, which belongs to the "private" type, and then the heroine's passionate commitment, by the collapsed wall to look at each other, which is contrary to the rituals. Her passionate pursuit of love is in direct conflict with the traditional feudal rites, which ultimately leads to her husband's repudiation and her brother's ridicule. Therefore, this poem is also called by Zhu Xi as "a work of lewd running".
