No, it's not just the entire Hanhai, it's the confidence of the whole of China abroad! With the trade frictions between the two countries already so prevalent, an incident like this would prove fatal, as even minor financial fraud could lead to a stock price plummet that shakes confidence in the corporate image of all Chinese enterprises!
If Hanhai collapses, my uncle and aunt have their subsidiaries and subordinates—precisely those who were just purged by Qin Zhiyou. They think that with such a major incident, Qin Zhiyou will certainly have to resign to take responsibility, and they can return to take over Hanhai. Even if Hanhai collapses, the money they've embezzled before would be enough for them to start over with a subsidiary. But in either case, it's difficult for Qin Zhiyou to escape blame; he will suffer the most!
