The Ching family is an affluent family that produces textiles for the royal family, the govt officials and the army during the Tang Dynasty. Circumstances force the Ching's 4th son, Ching Chi Hin to marry Dun Ju, the daughter of a Tibetan general. However, their relationship is marred by misunderstandings and hatred for each other. The two remain in a loveless marriage, with Dun Ju wanting to return to Tibet and Chi Hin nicknaming her "stupid pig" because her name Dun Ju pronunciation sounds the same as "stupid pig" in Chinese. One day she runs into Luk Dung Jaun, a Tibetan govt official on the streets of the Tang capital. He tells her he is on a secret mission and asks for her help, promising that he will take her back to Tibet once they have finished their mission. Their mission is to find the long-lost illegitimate son of the Tibetan Emperor. The clues to finding this person is a gold butterfly pendant, a piece of jade and a birthmark on the person's chest.
