Zhao Jindi only knew what Liu Zongzhen looked like when he was a child. Only Lin Qiuying knows what Liu Zongzhen looks like when he grows up. Before Luffy appeared, Liu Zongzhen never went home.

Lufei realized that the Civil Affairs Bureau had made a mistake because he had never married Lin Qiuying. Later, in the Liu family, Lin Qiuying pretended to be husband and wife and watched.

Lin Qiuying admitted that Liu Fei was Liu Zongzhen, and the Liu family did not doubt it at all. Because how can a wife not know her husband? In fact, when Lin Qiuying first met him, she told him bluntly that he was not the second son of the Liu family. Only later, I acted with the police.
