Everyone knows that grandma Ye Shurou has been fighting for half her life, but no one knows that Zheng Musheng's journey to South Asia has been a purgatory at every step. Parting in troubled times is just for the safety of his wife and children; fighting alone is just for the sake of a foothold for his fellow villagers. I met Xie Nanzhi at a young age, and from being disgusted with each other to being dependent on each other for life and death, they protected each other for half their lives in the name of brother and sister. He spent all his blood and braved the storms in South Asia, and finally welcomed his beloved home with glory all over his body.
