Chinese girl Lin Wanxing and her British husband Elias formed a cross-cultural family in London and raised sisters Elena and Lillian. They integrate Chinese traditions into their daily life, from Spring Festival lanterns and Chinese Valentine's Day sachets to Chinese enlightenment, and they often take their children back to China to experience the culture of their homeland. Elder sister Elena transforms into a "little Chinese teacher" and shares Chinese stories on campus; younger sister Lillian follows in her elder sister's footsteps and gets closer to traditional culture. The couple guarded them with love, making their small home in London, the foggy city, full of the warmth of family and the tenderness of the blend of Chinese and Western cultures, writing an ordinary but eternal chapter of happiness.
