"The Scent of Sophora Flowers in May" is a masterpiece of realism. On the frost day, Chen Ping, a "non-blood father" who was abandoned by his ex-wife, sold his old house and his father-in-law's coffin to collect 37,000 yuan. With the obsession of "returning the mother to the children", he and his twins went to Beijing to find their relatives. A cinnabar mole behind Zuo Yin's ear became the password for father and daughter to recognize each other; subway singing, bombings and assassinations, and rich second-generation conspiracies followed one after another. Motorcycle girl Lin Xiaoxiao, judge Lin Zhengguo, and homeless boy Xiao Shitou use justice to unveil the "accidental death plan" of real estate master Shen Mu. From Wuqiao Village to Wangjing SOHO, from frost to first snow, little people help themselves and each other in the steel forest of the city, using law and love as torches to illuminate the truth and the family ties beyond blood ties. When the gavel fell, the mother returned, and the children grew up, Chen Ping wrote "father" into the law and into the hearts of the people - after searching for relatives, love finally found its way home.
