Q. Can we think of examples of cultures that were not tolerated in Korea in the past but became accepted in recent years?

I think the culture of gender in the profession has changed. For example, in the past, we thought women should cook, but today there are many male chef’s and there are many male chefs and there is little discrimination against women by gender.
Also, in the past, only the name of a father was followed, but today, you can think of it as discrimination, choose a child's last name, and follow both names.
