You can't judge a tree by its bark.
人不可貌相。Clothes do not make the man.
人不在衣装。To be both a speaker of words and a doer of deeds.
既当演说家，又做实干家。Variety is the spice of life.
变化是生活的调味品。Bad times make a good man.
艰难困苦出能人。There is no royal road to learning.
求知无坦途。Doubt is the key to knowledge.
怀疑是知识的钥匙。Sharp tools make good work.
工欲善其事，必先利其器。
