What does Zhang Youyi mean by getting rich?

This man's fortune refers to the act of using the hoarded military supplies to sell at high prices in difficult times of war to obtain huge profits.

Zhang Youyi, as a man with certain economic strength, should have supported the country and cared for the people when the country was invaded by foreign enemies and the military and civilians were struggling to resist Japan. However, he chose to hoard military supplies and sell them at a high price at a critical moment to make huge profits. It not only violates social morality and national justice, but also aggravates the hardships of the military and civilians and brings a greater burden to the country.

Therefore, Zhang Youyi's behavior of making a fortune has been widely condemned and criticized, which is considered as a manifestation of lack of social responsibility and patriotic feelings. At the moment of national peril, everyone should think of the interests of the country instead of taking the opportunity to seek personal gain.
