The tiger demon Sanniang and the monk Gu Yansheng have been together for three hundred years. From a warm relationship when they first met in Changbai Mountain, to the mutual protection and dependence in the courtyard in the early days of the founding of the People's Republic of China, to the life and death of joining hands to fight against the Collecting Relics Society, they have always protected each other through ups and downs. The two people who accumulated merit unexpectedly welcomed their half-immortal child Gu Niansheng. From then on, the family of three began a journey around the world, accompanying each other with love and doing good deeds. They vividly interpreted the warmth of human fireworks and the beauty of being together, and wrote a warm story that spans race and time.
