The Yangtze River at Chongqing has mysteriously turned scarlet this week.
Amused locals are collecting souvenir bottles of the tomato juice-colored water.
The contrast is greatest where the polluted Yangtze (left) meets the Jialin (right).
No one is sure why the river has changed color, but this is not the first time something like this has happened. When a dye producing company dumped stocks into the Jain river, the result was described as “hellish”.
