Yang Qixiang knew a bailiff at the Governor's Office, who happened to be a relative of his, and received a message from him. He learned that Hen Lan had been imprisoned, and what's more, the charge was conspiring against the Prince. He was so frightened that he immediately wrote a letter of divorce and divorced Hen Lan!
Hen Lan had been waiting for Yang Qixiang to rescue her, but instead, she received a letter of divorce. She was so infuriated that she cursed loudly in her cell, but sadly, no one paid her any attention.
The jailers found her tirade merely amusing.
If it hadn't been for the Emperor's decree of a general amnesty, she would have had to spend her entire life in prison.
