Physicist Li Wei and his novelist wife, An Mei, just want a quiet life filled with lazy Sunday mornings and late-night cuddle sessions. Unfortunately, Li Wei is the baby brother of the five formidable, overprotective, and eccentric Li sisters who run the Wu Long Group.

When your sisters are a CEO who treats family dinners like a board meeting, a national taekwondo champion who can beat you up in a hundred different ways, and a celebrity supermodel who gets drunk and crashes on your couch, a quiet life becomes a mathematical impossibility.

Adding to all the chaos is An Jing—a university student and An Mei's little sister—with a wide variety of useful skills and a versatile moral compass.

Come and enjoy the stories of Tianjing City with this crazy and chaotic family, filled with love, comedy, and wholesomeness.
