If unfortunately encountering an offshore flow, do not try to swim backwards but continue swimming parallel to the coast until encountering waves from outside hitting and bringing back to the shore.

For those who do not know how to swim, or are exhausted, not physically enough to escape the upstream, try to swim parallel to the coast, or signal to the rescue or nearby people for rescue.

In addition, visitors should not spend too much time in the sun before entering the water. Do not let your stomach be too hungry or too full. Do not hold your breath for too long when diving.
