Thousands of tons of oil have been leaking from the oil tanker Hebei Spirit after it collided with a barge on Friday.
Emergency workers have been battling to stop the slick, said to be the country's worst, from harming local wildlife...
... but they have not been completely successful - the spill is affecting areas used by migrating birds as a resting place.
There are fears it will also reach scenic beaches and fish farms.
Coast guards have been spraying chemicals on the slick in an effort to disperse it.
But some beaches are already contaminated with the crude.
