Yesterday, when Chen Hui was pouring hot water, he poured a lot into his wrist by accident. Although he felt great pain, but he didn't know what to do. I happened to see this and immediate gave him first aid. Firstly, I asked him place the burns under running water for 10 minutes. After that, I put some cloth in cold water, squeezed the water out and placed them on the burning area over and over again. Finally, I covered the burns with the clean bandage. Gradually, he felt much better, that made me happy and proud of myself. Chen Hui expresses his thanks and said he would gain some knowledge of first aid so that I could offer help to others when needed.
