真功不露相露相非真功
[zhēn gōng bù lù xiāng lù xiāng fēi zhēn gōng]
'True ability remains unseen; revealed talent is not true skill.' Originating from martial arts philosophy, this saying encourages modesty and warns against boastfulness. It emphasizes that genuinely competent people don’t necessarily seek attention or show off their abilities but remain humble and reserved.
