I Know Who You Are (2026 film)

In 1949, during the days leading up to Proclamation of the People's Republic of China, Feng Jingbo, a commissioned Lt. Colonel of Bureau of Investigation and Statistics (BIS) with a code number 5182, receives an order from his superior Xue Jiankun to stay behind to collect intelligence, while others retreat to Hong Kong and Taiwan. Xiao Dali, a dedicated and stubborn local public security officer of the new republic, becomes highly suspicious of Feng during the the Campaign to Suppress Counterrevolutionaries. He believes Feng to be a Kuomintang sleeper agent because of the latter's unexpected familiarity with ceremonial cannons, despite the guise of a schoolteacher. Xiao thus moves into the same hutong where Feng lives, keeping his suspect under constant surveillance.

Over the next 35 plus years, against the backdrop of China's monumental historical shifts, from Great Leap Forward to Cultural Revolution, Reform and opening up, Battle of Laoshan, etc., Xiao plays cat and mouse with Feng. The two men grow old side-by-side as ordinary neighbors, locked in a silent, bitter ideological rivalry that defines both of their lives.

Unbeknownst to the two, BIS has been reorganized in 1955 and its spymaster Mao Renfeng passes away in 1956. Feng's former boss Xue has become a rich merchant from Hong Kong and has been courted by the United Front Work Department in the 1960s. Years later Feng meets Xue again at a wedding event, but is quite forgotten by the Xue. After jogging Xue's memory and learning the latest, Feng finally decides to confess to Xiao and the two families become in-laws due to their children's romantic bonds.

The film was released in China on June 19, 2026. On July 3, 2026, it was released in the United States.^[5][6][7] Achieving a score of 7.5 on Douban, the box office has not been satisfactory and is said to be caused by the director's much earlier insult towards the audience's intelligence.^[8] The movie is said to have been censored for several places not according to the director's will.^[9]

The film's audience reception was described as mixed.^[10][11] Hubei Daily compared the film with Dear You (2026), arguing that it placed "excessive emphasis on historical narrative at the expense of emotional engagement",^[10] while World Journal reported that common criticism focused on the screenplay's pacing, narrative style, and period setting.^[11]

Michael Ngan [zh], writing for Mirror Daily, argued that the film's poor reception reflected "intensifying tensions between the grassroots and the elite", as working-class audiences had little interest in a "didactic" film and resented China's entertainment elite.^[12] Steven Tian of The Storm Media wrote that the film exemplified "a common approach in contemporary Chinese cultural works beneath its commercial packaging", which "downplays ideological confrontation in favor of emphasizing a community with a shared future in which 'you are part of me, and I am part of you'", presenting "a subtler form of propaganda by transforming historical trauma and questions of identity into a warm, everyday narrative".^[13]
