What about burping? It's been a day, and I can't stop.

You can hold your nose and open your mouth to drink warm food, such as Jiang Shui and pepper water. Then try to hold your breath, and when the next burp comes, do a swallowing action and repeat it several times.

If you want to avoid burping, try not to talk when eating, don't eat too fast or too cold, eat less gas-producing foods such as beans and drink less carbonated drinks.

Extended data:

Flatulence and heartburn can stimulate the diaphragm, which is the main cause of intractable hiccups. Cure these gastrointestinal problems and the hiccups will disappear.

If hiccups can't stop on their own and are accompanied by a burning sensation in the stomach, chest or throat, you should see a doctor.
