A student is back in the Karen state, a place that was severely impacted by the civil war in their hearts, stereotypes happen, which leads to discriminating against the Burmese kid, who is still young and doesn't harm anyone else. We heard about some misunderstandings among the students, so my friends and I went back to give peace education training, which helped the students become more open-minded and better understand who is causing the trouble in the place. The students then started to accept the diversity and began gradually live in a peaceful way inside the community. In this circumstance, I was working as a mesosystem.
