What kind of impression does the walking posture leave on others?

Some people lean forward when walking, which will reveal a feeling of confidence, or deliberately keep a low profile, "I keep a low profile but I won't say it." Such people are generally modest, don't like to show their faces, and keep something in their hearts, but sometimes the real master is probably the old man who plays chess with his hands behind his back in front of your house. You can't judge a book by its cover. "Dogs that bark don't bite." Dogs that really bite are watching.
