The issue of violent demolitions isn't exactly fresh news anymore, and it's not surprising that the members of the Qin family chose such a tactic. At least when Su Yanyi received the message, she showed no surprise, as if she had anticipated this step all along. Of course, one could also say that she had calculated this step well in advance.
She had people spread false rumors that this area was going to become part of the city district and inadvertently stirred up some greedy individuals to cause trouble for the demolition efforts, dragging their feet in hopes of gaining more. This undoubtedly infuriated several people from the Qin family, leading to the current uproar.
