Han XiGuang clicked his tongue, feeling very unpleased seeing how his mother had set up a trick that made Su Yi to be mocked in front of the others. He could tell his mother hadn't done it out of malice. Most of the guests were curious of Su Yi while some others knew her from the tv broadcast and knew she is the daughter of Wu Family. The heinous Wu Gong who had killed many infants are frown upon and Su Yi who is his daughter is grouped to be as the same criminals who had sold those drugs even if she knew nothing about it and even if it had happened when she was younger.
He could tell how his mother would see this. Not only does she want Su Yi to feel welcomed, she wanted those rumors and the frown others had while looking at Su Yi to be gone in an instant. The fastest way to do so is to set up and example of what would happen when someone dared to bring up the matter between Wu Gong and Su Yi or even showed an antagonizing behavior toward her daughter in law.
