Madame Ruan was the proper wife, and she had never let Qin have her own way before. The Ruan family had acknowledged only her as their daughter-in-law, and she was the most respected woman in the clan. Even if she was stuck there as a prisoner, she would still maintain her poise and her status. She was a proud woman and would never bow to Qin. Even if she died, she would remain more respectable than Qin.
When she saw Madame Ruan's attitude, Qin was furious. She had nothing on her now, but she was still acting as if she was the main wife and the most respectable woman around.
"Go, go get that old witch down here!" Qin shouted to her maid.
She would bring her before the old man's photo and humiliate her!
They were all maids of the mansion, so obviously they were more loyal to Madame Ruan than they were to Qin. In fact, they had little respect for Qin.
