My hobby may be very special among my friends ... that is: collecting all kinds of soaps. When I was very young, I was probably just climbing. Many old people will play a game: put many objects in front of the baby and see which one the baby will pick up to play with. There are about four or five drawers of soap at home now. They are all collected from primary school, and the fragrance of some soaps is still very clear. When I was in primary school, I didn't have much change, so I could only buy some international brands of "Nais" ... or a set of five-dollar transparent soap, which is still crystal clear today. When I grow up, when I travel abroad, I will also buy a lot of soap intentionally or unintentionally. There are many soap gift boxes in the airport duty-free shops, and some tourist attractions will also have soaps engraved with wonderful patterns for sale. Take out these soaps from time to time and ask about the aroma and feelings, and you can go back to the original time and scene ~ soaps are also a good way to keep memories. Most importantly, it is much cheaper than perfume.
