Early life
Princess Xiangcheng is speculated to be born in 621 in Chang'an; the identity of her birth mother is unknown.
The princess was renowned for her filial piety and kindness, and her actions consistently reflected proper rituals. Emperor Taizong frequently issued edicts urging the other princesses to regard Princess Xiangcheng as a role model.
Married life
According to custom, a princess was not allowed to live in her husband's household after marriage; instead, a new residence—a princess's mansion—was to be constructed for her. However, Princess Xiangcheng rejected this arrangement, stating, "A daughter-in-law should treat her parents-in-law as her own parents, serving them both morning and evening. If we do not live together, the customary duty of attending to them at designated times will be compromised." Consequently, instead of building a new residence, the authorities simply renovated Xiao Yu's mansion on Kaihua Lane, adorning its entrance with paired halberds to meet the standards required for a princess's residence.
