Fifty years ago, Tulou was invaded by mountain bandits. The tribesmen stayed behind closed doors for a long time and relied on food reserves. Most of the farmland was abandoned, and the tribesmen struggled to make ends meet. The old man from the big house in Tulou took the initiative to ask for help and left his hometown for help. After solving the bandit crisis, Mr. Dafang left his hometown again and went south to look for development opportunities, gradually making Dafang one of the top ten rich people in Nangang. Dafang reached an agreement with the clan leader in order to ensure that the century-old Tulou family fortune would not fall into the hands of other families: Lu Chunyan, the granddaughter of the eldest family among the four families, would be exchanged with Lu Dongmei, the youngest granddaughter of the eldest family (actually a hostage exchange). The Tulou was facing demolition, and she was recalled, only to find that her family had already approved that her sister, Lu Dongmei, the granddaughter of the eldest family, who grew up in the Tulou and was loved by the elderly, was the actual spokesperson. Lu Dongmei seems to be gentle and kind-hearted, dedicated to protecting the earth buildings, but in fact she has secret connections with Dafang and external capital.
