Zhao Tiehua, who grew up in the countryside, returns to the Shen family and finally reunites with her biological family. The resilience and straightforwardness honed in the mountains and fields since childhood made her initially unaccustomed to the cautious life at home. Facing the long-standing conflicts and misunderstandings in the family, she did not back down, but instead used simple sincerity and courage to resolve the estrangement among family members little by little. She always protects her kind younger sister Shen Mingzhu, and also uses practical actions to let everyone understand that the most precious thing among family members is not wealth and status, but mutual trust and candor. In the end, the misunderstandings that had been hidden for many years were unraveled one by one, and the family put aside their heart-knots, regaining long-lost warmth and harmony.
