Is there any way to stop me from laughing?

I also have a low laugh and often laugh wildly. When I was a child, I was kicked by my teacher many times, and all kinds of penalty stations were made. People who shouldn't laugh at work now often laugh. Summarized two experiences:

1, pinching yourself is the most immediate. Places that others can't see, such as pinching your hands or legs, must be cruel and painful to laugh.

If you can't work hard, you must think quickly. Think of an unhappy thing or a person in advance, and think directly every time you want to laugh. For example, every time I try to control myself from laughing, I will think of dumping my ex-boyfriend's name and stop laughing when I think of it. Let you think of unpleasant things or people in advance, and then you can think of them instantly every time you want to stop laughing. You don't have to think about them on the spot, you will definitely be surprised on the spot.
