I pass by this street every morning when I drive to work. This street is actually at the corner of my house. I used to see a lot of rubbish were thrown at the road side, and it was even more trash during the spring cleaning season right before CNY. One fine evening, when we went out for dinner, my husband asked me to take a look at the sign board which some one put there.
I guess those people who still litter do not afraid of life threatening decease, poor and bad luck.
Anyway, everyone should have the Civic Pride to care for the hygiene and the beauty of the environment. It is always our job to pack our own trash and dispose it properly.
