In the seventies in Kaoshantun, the domineering female hunter Lu Zhixia threw out a five hundred yuan betrothal gift, and married the down-and-out frail scholar Xie Qingyan home to be a matrilocal son-in-law. The whole village laughed at her for picking up a useless young master, but no one knew that inside this frail shell, there was hidden the brain of a top chemical industry big shot. From handmade peppermint soap selling out wildly in the black market, to rose cold cream sweeping the county, and then to fleeceflower root shampoo sweeping the provincial trade fair, Xie Qingyan relied on hardcore technology to lead her all the way to counterattack, slapping blood-sucking relatives in the face and kicking away black-hearted opponents, turning the small mountain workshop into a well-known daily chemical group.
