"Seventies is a Little Tiantian" is a sweet and warm story rooted in the northeastern countryside of the 1970s, full of fireworks. Tang Tian, a modern senior architect, accidentally passed through the book and became the cherished youngest daughter of the Tang family. In the original book, the Tang family ended tragically. She relied on modern thinking and the family's preference to outsmart the scumbags, set up a stall to start a business, hoard houses to get rich, and helped her brothers find a good match.
