What should I do if people's ideas are old-fashioned?

A leopard cannot change his spots. People's conservative ideas can't be changed overnight, and they can only seek common ground while reserving differences.

Let them get in touch with new people, things and things, take them out to see today's developing society, compare their youth with today's times, guide them, accept new things, buy them some modern scientific and technological versions of daily necessities, and enlighten them that everything must be developed to make progress and slowly change their minds.

Constantly stimulate their thinking with new things.

Constantly influence their thinking with trendy things.

Constantly changing their minds with facts.
