Jiang Xiaoyue's fiancé was named Li Jun, a young man of noble birth. They had been childhood friends, and their affection and forthcoming marriage seemed to be a natural development. However, when Li Jun, driven by his privileged background, made an egregious error during a visit to Jiang Xiaoyue by flirting with some other female soldiers, he was immediately beaten by the quick-tempered Jiang Yun and then sentenced to labor reform for his lascivious behavior.
Of course, their engagement was subsequently cancelled.
The Li family refused to accept this, bringing up past disciplinary actions against Jiang Xiaoyue, which resulted in enmity between the two families. This feud in turn impacted Jiang Xiaoyue's prospects for marriage.
