No wonder Gu Juan was running to Old Sir Gu's house every day back then; it was clearly a case of unsolicited flattery, either treachery or theft.
Although there's no evidence, it's basically certain that this Taiwanese businessman is no good, and even intended to sabotage the transformer factory in Qin City.

"So now, she should have already left the country," Liu Jun said, "and it was by smuggling too."
As such, even if we wanted to investigate which country she went to, we wouldn't be able to.
"Left the country?" Yang Yunhai's lips curled slightly, "Unless she decides never to return."
Su Ziqiao and Liu Jun exchanged a glance; whenever the Boss shows that expression, it means he's genuinely angry, and the consequences of Brother Hai being angry are something quite scary.
