Zhang Qiling went to work in France and controlled everything secretly. Wu Xie was abused and tortured in China and refused to reveal anything that could threaten Zhang Qiling.
When he came back, he pretended not to know and tried again and again to make him give up.
He fell in love with another woman and had his own child.
