So, did you ask how we managed to keep even our void decks, corridors so clean?
Ok, here's the secret, now it's 'leaked':-
Look, this photo shows a classic example to keep our living environment clean. This small holding area is where junk mails are 'collected'. These mail boxes are for the residents living in this entire block of housing flat. The design creates an easy access even if small or short children wants to help their mom or dad to check the letter box. It's not a problem now. Even if they live on the 12th Floor;)
There is also an extensive use of garbage bins, or trash cans islandwide:) More importantly is to educate the public to throw their unwanted junk mails and flyers into the trash bins.
it's bad PSI 102
it's choking:( bad!
