Empire of Dust

Lao Yang and Eddy both work for a company called CREC (Chinese Railway Engineering Company). With Eddy (a Congolese man who speaks Mandarin fluently) as an intermediate, Lao Yang is forced to leave the camp and deal with local Congolese entrepreneurs, because without the construction materials the road works will cease. What follows is an endless, harsh, but absurdly funny roller coaster of negotiations and misunderstandings, as Lao Yan learns about the Congolese way of making deals. (imdb)
