I used to not believe that "the face reflects the heart," until I saw a real case:

A friend's ex-wife, before age 35, had a gentle temperament and a face as clean as a peeled egg. Everyone said she had a face that brings good fortune to her husband.
Later, she had an affair with a big brother who made money through shady means, and became his mistress.
Meeting again two or three years later, her face clearly showed more gloom and ferocity,
She had grown horizontal flesh, with complex lines, completely losing her former cleanliness.
It's not unusual for temperament to change, but to actually grow horizontal flesh on the face? That's very mysterious.
The paths you've walked and the things you've done will eventually be engraved on your face.
Do you have real-life examples of "the face reflects the heart" around you?
