How was the transfer of cultural achievements to new generations in primitive society carried out and how is this happening now?

In the ancient world, most often the transfer of cultural achievements was transmitted using a method.
That is, the master taught the young student what he had already learned himself and what his ancestors had taught him. In addition to a personal example, buildings and structures were transferred as cultural values; also, when writing appeared, records of events were kept. Both poems and letters to lovers from Pharaonic times have reached our times.
When typography appeared, books became one of the ways to convey cultural values.
Don’t forget about music, cinema, paintings and sculptures created by artists.
Today, literally any cultural event, even one-time one, can be recorded in digital format and stored the days of posterity.
So, for example, each performance is a new presentation and improvisation – and, if before people could judge a particular performance, only having been there in person, today you can watch everything in the recordings.
Nowadays, good conditions have been created in order to preserve and transmit all cultural values ​​for new generations.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
