At my son's first birthday party, my father-in-law, who had always been calm, drank too much and cried while holding my son, but he kept shouting, "My Lin Feng, grandpa's great grandson." Lin Feng is my wife's legendary genius brother who died young. The entire banquet hall fell silent for an instant, my wife turned pale, and I, like an outsider, had my heart clenched tightly by an invisible hand, almost suffocating. I realized that I was not only the son-in-law of this family, but also seemed to be a "meal replacement" for the undead.
