Littering is throwing slogans from upstairs to downstairs.

It's a mess to throw things upstairs to the ground floor (where we live). We want to put stickers on the residents upstairs and tell them not to litter and write whatever they write.

Notice: 1) My brother-in-law is in the police dog training base of the Public Security Department, and will regularly conduct basic training in this corridor. The specific way is to absorb the odor characteristics of objects thrown downstairs, and then search upstairs layer by layer to find matching households; Confirm the door of the household first, and then confirm the human body odor characteristics of the household. Aggressive big dogs are a threat to human beings. For the safety of your life, please keep calm and refrain from unnecessary actions and language during the verification process to ensure your life safety. Several days a week, the police dog will wait for you at your door, and you can respond politely.

2) The physical evidence identification major of Public Security University is about to conduct DNA biometrics here. The samples are food, hair, cigarette butts and toothpicks thrown upstairs; Because biological DNA features are more advanced private information than fingerprints, addresses, home phone numbers, and customer information necessary for survival, it can predict your future fatal defects such as diseases, cancer, and personality. Please go upstairs and claim it before publication, and ask you to bear the inspection fee in full. 3) Your fingerprints will also be made public, and others can imitate your living fingerprints on fingerprint identification equipment. If you have any comments, please come as soon as possible and put forward your application and requirements. 4) Install microwave, infrared and ultrasonic comprehensive positioning test instruments every three floors to locate, photograph and record the moving objects in space in real time, and use high-pressure jet, controlled explosion and laser beam to eliminate and burn the moving debris in space. For your safety, please take the initiative to avoid the laser beam to avoid accidents. 5) For the garbage thrown upstairs, according to the degree of pollution and their respective weights, the property fee will be deducted from all upstairs residents on a regular basis.
