As a Chinese who does a bit of Wikipedia editing, there is a right way!1!! just that the wrong ways can also work but often work less well. For example, with this grip, your thumb and knuckles have to do a bit of extra force to rotate the sticks as the “levering point” is at the end of the chopsticks, which is quite far. Meanwhile, in standard grip, your middle finger (I just realized that it had to be that finger lol) acts as a “levering point” and significantly shorten the distance to your thumb and knuckles, resulting in a lot less force being needed.
