First, read the English article below.

Look through the available douching products at your local drugstore to choose an option that looks best for you. Avoid any solution that contains scents or dyes, as these are much more likely to cause an infection. If you prefer, you can create your own douching solution at home using vinegar and only buy a squeeze bottle at the store for application. If you bought a kit at the store, follow the box directions to prepare the douching solution it came with. Typically you will need to use a quart of water to prepare it. If you are making your own at home, mix one part vinegar with three parts water, in an amount equal to at least two cups. Follow the directions on the box to do this, or simply pour the solution into the squeeze bottle. If all the solution doesn’t fit, fill it as high as you are able and then add the rest later. Douching isn’t the messiest thing in the world, but it could be under certain circumstances. To prevent spilling any of the solution, get into the shower or bathtub for the entire process. You’ll likely want to shower or bath afterwards anyway. Insert the tip of the squeeze bottle or douche pouch into the vagina, and squeeze it to release the fluid. Continue rinsing the inside of the vagina until you have used all the available fluid. Use a mild soap and warm water to wash the outside of the vagina as you would normally during a shower or bath.  Your goal now is to wash off any of the douching solution left on the exterior of your vagina. The douching solution is relatively harmless on any other part of your body, so rinse it off if it came into contact with anything else but don’t worry about it too much. Follow up with any post-douching cleaning activities you deem necessary. Clean out the douching pouch/squeeze bottle and store it for later use, and clean up anything else you might have made a mess with while concocting your solution.
