Yue Fei's words 900 years ago are still the true words of warning, the wisdom of ancestors and the broad civilization of 5,000 years. Yue Fei means: civil servants are not greedy for money, military officers are not afraid of death, and the world is at peace. "Not greedy for money" means "a gentleman loves money and takes it wisely". Love for money is understandable, but it is aboveboard to get what you deserve, and you can't become greedy for money. Otherwise, it will violate the way of being a man, and will eventually bring disaster and destruction to yourself.
