This book uses the first-person perspective of senior real estate consultant Zhang Xiaoyu, recording the ups and downs of the real estate industry and the various changes in the world in the ten years since she entered the industry in 2004. The story begins with industry training in Wenzhou, and then travels to sales offices in Lin'an, Haining, and Yuhang, witnessing the complete ups and downs of China's real estate market from the golden age to the regulation cycle: the enthusiasm of real estate speculators to buy goods in bulk, the fierce conflicts in housing troubles, the market freeze under the purchase restriction policy, and the rush to buy when the market picks up. All the epitome of the wave of the times are concentrated in the welcome and delivery next to the square inch sand table. The book describes the bitterness and sweetness of real estate sales: the grievance of being cut off by colleagues, the fear of being harassed by unscrupulous customers, the absurdity of encountering scams, but also the warmth of being trusted and entrusted by customers, the joy of placing the first order, and the deep friendship formed with colleagues. The protagonist always adheres to the "people-oriented" original intention when she entered the industry, and sees the ordinary lives behind each house: old couples who remarry in their later years, migrant couples who try their best to bring their children to the city, young people who give up their marital home to treat their grandmother. All the longings and struggles for home have taken root under her witness.
