because he saw someone after taking a bus for breakfast and lost his garbage. Reporters learned that the 12 year old boy is a member of the school environmental protection institute.
Cao Chenqing introduced his work to the bus fleet. The 79 motorcade was very interested in it and tried to install the sample he designed in the carriage. Cao Chenqing told reporters that in October last year, he thought about making a special garbage bin for buses. When he was away from school, he measured the diameter of the armrest with his grandfather's ruler. "My original idea was to punch holes in the trash cans, and use a hoop to fix the trash cans on the back door handrails, but that trash can be easily damaged." After many discussions, he and Xing Xifeng, the instructor, designed a iron hoop and a ring, put the ring on the armrest, fixed the trash can with iron hoop, and inserted the ring directly.
