Being a low-key person "is to be modest, calm, unassuming, not showing off, and advancing and retreating moderately." The so-called "wood is in the beauty of the forest, and the wind will destroy it." "High-profile work" means that when a person sets a goal, he must resolutely implement it. Do it when it's time to do it, act boldly and decisively, and don't stick to other people's comments and opinions.
