"人们从未改变只是变得更善于隐藏他们真正的样子"

Simplified Meaning:

People often don't actually change their true nature or who they are deep down. Instead, they learn how to cover up their real feelings or behaviors better as time goes on. Think of a person who is naturally very selfish. At first, they might show their selfishness openly, but after getting negative reactions from others, they learn to hide it better. They may start pretending to be generous to avoid criticism, but inside, they're still thinking of themselves first. In real life, you might encounter someone who seemed really kind and friendly at first, but over time you notice that their actions don't match their words. They're still the same person they always were, but they’ve learned how to disguise their true nature better. Understanding this can help you be more cautious about trusting people too quickly. It also serves as a reminder to look more deeply at someone's consistent behaviors over time rather than just their surface appearance.
