"Not One Less" is not only about the poor in China's remote rural areas, but could be dedicated to them; we sense that Zhang Yimou, the director of such sophisticated films as "Raise the Red Lantern" and "Shanghai Triad," is returning here to memories of the years from 1968 to 1978, when he worked as a rural laborer under the Cultural Revolution. His story is simple, unadorned, direct. Only the margins are complicated.
