So this is called stilting. It's a thermal behavior that you and I do if we cross the beach, we jump onto a towel, somebody has this towel -- "Sorry, I've jumped onto your towel." -- and then you scuttle across onto somebody else's towel, and that way you don't burn your feet.
这种手法叫“踩高跷”。这跟你我穿过沙滩时 避免脚被烫到的行为是类似的， 我们跳上一条毛巾，不知道谁的毛巾 —— “抱歉，我踩到了你的毛巾。”—— 然后你又跳到另一个人的毛巾上， 这样你就不会烫到自己的脚了。
