One of the primary historical contexts for Tungus is the "Siege of Changchun," a hidden history of the 1948 Kuomintang-Communist Civil War that neither side would like to recall. In this quiet war without fire and smoke, hundreds of thousands of civilians, caught in the middle ground of beliefs and ideologies created by the military encirclement of the two armies, vanished in a primitive way - by starvation. In this film, as two soldiers from the Korean Independent Division of the Chinese People's Liberation Army try to flee Changchun, they gradually realise that they are in an overlapping time and space with that of Jeju Island, where the "Jeju uprising" has just occurred in the shadow of the Korean War. At the same time, a middle-aged scholar who refuses to flee the city of Changchun returns to the May 4th Movement of 1919 in an illusion caused by extreme hunger and subsequently makes new resolutions. In these forgotten historical narratives, Wang Tuo illustrates how hunger-led hallucinations from a shared mass experience lead to a collective conversion to "Pan-shamanism." In this conversion, he sees the Northeast Asian reality being reshaped by the power of the psyche mired in historical trauma. At the same time, the root of contemporary geopolitical dilemmas in Northeast Asia, buried deep in its recent history, are gradually unfolded and retraced.
