He has done everything he can to prepare for the exam, and now he is in a state of 'doing all that is humanly possible and waiting for fate to take its course'.

He admitted that it is difficult to execute the plan, saying 'it is easier said than done.'

He is truly a person who embodies the saying, 'A man of virtue will naturally attract admirers.'

This ancient proverb, 'know the other side and yourself, and you will not be in danger in a hundred battles', teaches us the importance of understanding ourselves and others.
