As for the home, the wastebasket trash can is mainly used to throw sanitary napkins and the like, but if your family is used to using paper towels instead of toilet paper to go to the toilet, or some elderly people use nonstandard paper such as newspapers to save money, then throw the wastebasket honestly to avoid blocking the sewer.
Some public toilets are not equipped with toilet paper or are often out of stock, so they need to bring their own. Few people will bring toilet paper that meets the specifications to go shopping. It's basically toilet paper. Toilet paper can't be thrown directly into the toilet. The reason is also mentioned above, so in order to prevent future troubles, it is required to throw all the toilet paper into the wastebasket.
