First, read the English article below.

The biggest risk associated with any stomach virus is dehydration. As a result, the most important thing you can do to help your body get rid of the virus is to keep yourself hydrated as much as possible.  You should try to get 8 oz (250 ml) of fluid every hour as an adult. Children need 1 oz (30 ml) of fluid every 30 to 60 minutes.  Drink slowly, taking small sips instead of large gulps. Fluids will sit in your stomach more effectively if you introduce them to your system gradually instead of all at once.     Drinking too much plain water as you recover can dilute the few electrolytes still in your system, so try to include an oral electrolyte solution in your drinking routine as you fight the bug. In addition to a loss of water, you are also losing sodium, potassium, and other electrolytes. An electrolyte solution can help replace some of those lost minerals, as well. Other good drinks to consider include diluted juices, diluted sports drinks, clear broth, and decaffeinated tea.     Avoid sugary drinks. Adding sugar to your system without also adding salt can make diarrhea worse. Carbonated, caffeinated, and alcoholic drinks should all be avoided, too.     If drinks are hard to tolerate, suck on ice chips or a popsicle, instead. As soon as your stomach feels ready to take on solid foods again, you should begin eating to restore any lost nutrients. While there is little scientific evidence to show that bland foods are inherently easier to digest than less bland foods, most people do seem to take to them better when nausea is still moderately strong.  A traditionally bland diet would be the BRAT diet, which includes bananas, rice, applesauce, and toast. Other decent options include baked potatoes without butter, bagels, pretzels, and crackers. You should only do this for a day or so. Bland foods are certainly better than nothing, but relying on them completely during your recovery will deprive your body of the nutrients it needs to fight off the bug.
