Shen Wantang sang opera for five years and saved enough money to redeem himself. But on the day of redemption, Gu Beichen sent someone to deliver a marriage certificate, asking her to marry into the handsome man's house and become his concubine. She tore up the marriage contract and threw it into the incense burner in front of him. Gu Beichen was not angry, but just smiled: What you are tearing up is the marriage certificate, and it is also the life of your whole family. Shen Wantang didn't know that her father's death was hidden in Gu Beichen's handsome mansion. And every line she sang was slapping the truth in her face.
