Who gives me some warm tips about tourist attractions, such as swimming on the beach and climbing mountains?

Beach swimming: (1) Don't use your body to measure the depth of the sea. Don't judge the depth of the sea by your body. Although water can be played, don't play. (3) Take a step back and go deeper.

Climbing a mountain: (1) The mountain is high and the road is steep, so you can win steadily. (2) I can't stand the cold at high places, so I need to wear more clothes at night.

Hey, there's nothing I can do. I hope these can help you.
