Directed by the well-established name of Chinese cinema, Feng Xiaogang, this period drama spans a period of nearly forty years, from the late 1940s to the early 1980s. Adapted from Zhang Ce's 1992 novel "Unrepentant Pursuit", the production uses Beijing as both a location and a backdrop that embodies the spirit of the period. In the film starring Lei Jiayin and Hu Ge, the two characters are dragged into an intricate relationship with each other throughout the decades that began with the establishment of the People's Republic of China and where social transformations chased each other. The relationship in question is not only a reflection of a personal conflict, but also the political climate and ideological tensions of the period. The China of the 1950s, 60s, 70s and 80s ceases to be a background and becomes a living force shaping the characters' destinies. The production questions the traces left by historical transformations on people's memory, conscience and identity. The film, which is the story of a pursuit or confrontation that lasts for decades, asks the audience what has changed and what has not changed over time, which truths decay and which ones survive. Feng Xiaogang's narrative mastery allows each period to feel its own texture, rather than compressing this wide period of time. It is a noteworthy production for those who love the historical drama genre as well as those who are interested in China's recent history.
