That family said that as long as Qian'e married into their family, they would give her 500 dollars as a betrothal gift. They would also give her the 'three turns and one sound'.
At first, Zhao Ni could not understand why that family wanted Qian'e to marry into their family. Later on, when she knew that that family had four daughters, she then understood that what they wanted was for Qian'e to bear a son to carry on the family line.
However, Qian'e had already removed her uterus during the previous incident and could no longer have children.
If that family found out about this, they would definitely break off the engagement. However, she did not know how Old Madam Qian had managed to persuade them to agree to Qian'e marrying into their family and also give her a generous betrothal gift.
It was possible that Old Madam Qian did not tell them the truth at all and was just tricking them, and throwing Qian'e under the bus for that bit of money.
