这句话哪里错了？可能有点中式英文，请帮忙修改

Just like a deaf man, who does not mind others that laughing at him; just like a blind man, who does not care about others that much better than him.

基本可以.注意一些细节：
1. a deaf 要有名词，deaf本身是形容词
2.确实用楼上所说，得有名词…………所以我修改了
3. care others 要有介词care about

句子缺少主语啊，just like sb 不能算是一个主语
你可以说He/she(这里要有个人称才行） just like a deaf ,do not mind……

others are laughing at you -> others' laughing at you
还有blind不一定不care吧，可以改成look at 或者mind或者bother to look at

Try to be like a deaf, do not mind when others are laughing at you;
Try to be like a blind man, do not care if others are much better than you.

你的意思是 学着像一个。。。
