试金之石可试金，金可试人

This proverb operates on two levels. On the surface, it explains the practical use of a touchstone (试金石)—a dark stone used since ancient times to test the purity of gold. On a deeper level, it makes a philosophical observation: money and material wealth are the ultimate tests of character.

Interpretations

1. Wealth reveals character: How someone handles money shows their true nature
2. Power corrupts: Access to resources can bring out both the best and worst in people
3. True friends remain: Financial hardship reveals who your real friends are
