Head shooting skills:

It is best to shoot at the same position as the photographer's glasses, so that the head shot will not appear perspective distortion. However, if Cao's head photography skill is fat, he can shoot from a slightly higher position, or he can point his head a little lower to make the photographed person look thinner.

Don't shoot people from below the face, it will make people look fatter. The timing of pressing the shutter when shooting is also important. Most people feel shy when taking pictures, so their expressions are the most vivid when they don't know that they are being photographed. So you don't have to tell the photographer when you press the shutter, so you can often take more vivid photos.
