The shortest is the mini sanitary napkin, with 1778 and 190, followed by daily use, generally 240, and 230 to 260. Starting with 280 at night, there are 290350410420 (338 in 7-degree space). I usually use 290 or 420. Then there is a special pants type sanitary napkin, which can be put on directly like underwear, and then used up and thrown away.

Under normal circumstances, it must be used daily during the day and at night. Change it every two or three hours during the day. If the amount is particularly large in the first two days, you can use 290 at night. It doesn't need to be too long, otherwise it's uncomfortable to cover your ass. During the exam, sit for more than two hours, stand up and pour out a pile. You can also use it at night. For night use, I use 420 more in the first two days and 290 less in the next two days. This varies from person to person! Then, the trouser type sanitary napkin can be used in the case of large quantity or outdoor sports.
