Qingwan River in southern China's Yulin city turned red due to waste discharged from nearby mills.
The video filmed on July 2 shows the Qingwan River running among the fields turning red.
According to local villagers, some mills in Dali Town discharged the waste upstream causing pollution.
The local environmental protection administration announced that they have found a dyed plastic bag with some red solid in the river.
They preliminarily confirmed that the pollution was caused by the dyes that were deliberately poured into the river by someone.
