Night Lights in the Community

Property fines are plastered all over the unit door, and garbage still appears on time late at night. The new security guard, Lao Zhou, didn't say anything. He bent down to tidy up every day before dawn, and placed a rechargeable night light next to the bucket. At first, some people laughed at him for being stupid, but on the seventh night when the lights came on, the garbage thrower suddenly felt his hands became heavy. At the end of the month, the corner is as clean as new. The owners suddenly understood - it turns out that the loudest advice never requires opening one's mouth.
