Before the prodigal son returns to gold, a good horse does not eat grass, and the prodigal son returns to gold. Eighty-one Dreams, written by Zhang Henshui, a great writer of modern literature, is also a famous saying used to describe some young men and women who have lost their lives to turn over a new leaf and repent and turn over a new leaf.
The prodigal son turns back to gold, which means that people who don't follow the right path are extremely valuable after turning over a new leaf.
