In this year's Piri-Cup, we will visualize each of these 'virtues' posted on SNS Pirika with everyone. On the special website, the 'Virtue Tower' grows by 1cm for every piece of litter picked up! On the final day of the event, a 'Virtue Tower' reflecting the achievements of all participants will appear. Why not join us in this challenge to visualize each person's small actions and work together with users around the world? ## Sharing 'Small Joys' Found Beyond Litter Cleanup This event also focuses on positive experiences found through litter cleanup. - It feels good to see the city get cleaner - Someone said 'Thank you' to me - Noticed the beauty of nature These 'experiences beyond litter cleanup' will also be shared as a posting theme, creating new value that goes beyond mere cleaning activities. ## How to Participate ### 1.
