On Sept 2019, I founded Beatles First-aid Group, aimed at spreading first-aid knowledge and skills. In order to operate this group, I contacted with Jinan Red Cross Hospital. I joined in the first-aid training and obtained the certification in June, gave a first-aid lecture to nearly 80 classmates in July, and organized 5 students to study CPR technique in August. Every weekend, I issued flyers in my neighborhood, urging people to raise the awareness of the importance of self-rescue.
