Who is the person who spreads traditional culture around you?

My little uncle counts as one. Yes, it's my husband's little uncle, my uncle, haha. According to my mother-in-law, their policies were still very loose when they were young. They opened a game hall at home and made a lot of money. My uncle's family is not rich. My mother-in-law wanted to help him and let him open a game hall together, but my uncle refused. He thinks that there are many children playing games in the game hall, and it is wrong to make money by this. In fact, my uncle is under great financial pressure and his family relationship is not very harmonious, because my aunt thinks that he has no ability to make money and will ridicule him. In addition to the game hall, there are other similar events. My mother-in-law lamented that my uncle was too single-minded, so she would be more passive economically. Hearing this, my heart is full of admiration for my uncle. In fact, it was not illegal to open a game hall in those days. Although citizens should have a certain sense of social responsibility, because it is not illegal, we can't take not opening game halls as a mandatory requirement for citizens' sense of social responsibility. But my uncle can take on additional social responsibilities independently without external pressure, so I think he is a noble and respectable person.
