Many folk tales have been handed down this way from generation to generation.
Tips
usage
Used for things that survive across generations: family crafts, recipes, secret techniques, oral stories. Compare with 代代相传 - same meaning, slightly more colloquial. It's a transparent compound widely used in modern writing.
memory
Reads literally: 世代 ('generations') + 相传 ('pass to one another') - 'generation by generation, passed along'.
