Another way is to hold your breath. First of all, we should block our nostrils with our thumb and forefinger. After taking a deep breath, shut our mouths. Hold it until we can't hold it any longer, and then let go. This method can make our nose thinner.
Another way is to press the alar on both sides of our nose with both hands, leaving only a little space. And then jump in place more than 20 times, less than 50 times. I often jump when I have nothing to do, especially at night. Stick to it for two months, and it will have obvious effects.
