'We Learn to Share' was founded by a 10th grader in South Korea named Elena (Korean name: Seungeun Lee) in 2021 because she realized a love for sharing what she had learned in school. Starting from 2022, 'We Learn to Share' has become the first and only international high school student-led organization in the entire world dedicated to educational volunteer activities. Elena has invited highschool students from different countries and schools all over the world (+ 30 schools from +12 countries) to this channel. Just watch and learn!
