What are some concrete examples of saying that thrift is the traditional virtue of the Chinese nation?

Thrift is always a traditional virtue, but it is called virtue when morality demands itself. When it is used to demand others or applied to others, it has a certain probability of becoming a derogatory term. Imagine if you are frugal to yourself and generous to your parents, wife and children, will anyone make irresponsible remarks? On the contrary, if you detain everyone, what do you do with the money? No one will spray the flowers you should spend, so spend them rationally.
