在我们的生活中,一天也离不了肥皂。洗脸用香皂,洗澡用药皂,洗衣服用洗衣皂。脸要天天洗,衣服也要勤洗勤换。衣服穿久了,由于尘土、油污和汗水的沾污会散发出酸臭味。带有油污的衣服是滋生细菌的温床。脏东西还会腐蚀、毁坏织物的纤维,只有经常洗涤才能使衣服延年益寿。古时候,人们在河边青石板上,将衣服折叠好,反复用木棒捶打,靠 In our lives, soap cannot be separated from one day. Wash your face with soap, bath soap, laundry soap. The face must be washed every day, and the clothes must be changed frequently.

Dirty things will also corrode and destroy the fibers of the fabric. Only regular washing can make the clothes prolong life. In ancient times, people folded their clothes on the riverside stone slabs and repeatedly beat them with wooden sticks.
