When the tide rises, you should leave the beach quickly to avoid being swept away by the tide.

If you are entangled, you should lie on your back on the water, paddle with one hand, and push away the water plants with the other.

If you suddenly get cramps while swimming, if you are close to the shore, you should go ashore immediately and massage the cramped area; if you are far from the shore, you should immediately float on your back and massage or pull the cramped area until the cramp is not serious. When the situation occurs, immediately use your non-cramped limbs to paddle and get ashore as soon as possible. If there are other people nearby at the time, call for help.
