Therefore, people will be given a great responsibility by heaven, so they must first suffer from their minds, work hard on their bones and muscles, starve their bodies, empty their bodies, and mess up their actions, so their patience has benefited them.

Translation:

Therefore, heaven is about to drop a great responsibility on such a person. We must first make his heart ache, make his bones and muscles tired, make him suffer from hunger, make his skin emaciated, make him suffer from poverty, and make what he does upside down, which is always unsatisfactory. Through these, we can alert his heart, strengthen his character and increase his talents that he does not have.
