Expose the other party? That's very difficult.
In front of the family, during a confrontation, Lu Dongliang would hardly give Lu Chunying a chance to speak. Therefore, Lu Chunying couldn't return to Greenwater City. She could only stay in Qi Qiu City.
Would "Lu Dongliang" possibly chase her to Qi Qiu City and try to harm Lu Chunying? You'd have to ask Qiu Luoye, and the three thousand Three-Headed People. Qi Qiu City was Li Qi's stronghold. In this territory, Li Qi didn't fear any master from Above the Clouds.
Until Duan Shaoxia permitted "Lu Dongliang" to enter the household, his identity wouldn't be truly confirmed. Lu Chunying merely had to remain in Qi Qiu City, manage her business, and maintain an attitude of not stooping to the level of a conman. That way, "Lu Dongliang" would be powerless against her.
What was Duan Shaoxia's attitude? She was under immense pressure.
"Xiuling, go and check for me again—is that Dongliang truly genuine?"
