Legend has it that when a pig is killed, it will feel sad and shed tears, thinking of the past and its own destiny. I replayed this scene over and over again in the replay library of my memory, just to prevent myself from crying due to sadness.
Someone asked me why I sing more sad songs, because I think joys and sorrows come first, and most of the time life is not smooth, and only a few are smooth. We pray for good weather every day and good fortune every year, but we are often not so happy. Happiness is the abnormal state, and unhappiness is the norm. So I can understand my mentor very well. I think my mentor's state is the state in life. Only when he is under pressure and burden does he have the motivation to move forward.
