### Chinese: 当我们身边有人倒下的时候，我们可以通过专业的知识去对他进行抢救，而不是傻傻地站在那里一动不动什么也做不了，这种无助的感觉太让人感到可怕了。
### English: When someone falls down around us, we can use our professional knowledge to rescue him, instead of standing there motionless and unable to do anything, the feeling of helplessness is so terrible.

### Improved English: When somebody falls down, we can conduct first aid with our professional knowledge, instead of doing nothing and only standing there; this helpless feeling is really frightening.
