“人不可貌相,海水不可斗量”这句话翻译成英文怎么翻译比较好?

这句话明显带有中国特色,如果从字面上翻译,比如：A man can not be known by his look,nor can the ocean be measured by a dipper。就成了中国式英语,老外未必能看得懂,如果能够稍加修改,比如译成：A man can not be judged by his appearance,nor can the water in the sea be measured by a bucket。或者：We can not judge a person by appearance only。再或者 You can not judge a book by its cover。(意思是：一本书的好坏取决于它的内容,而不是它的封面装帧的漂亮与否。)会相对好得多,更容易理解。
