My name is Wang RuoYin, from Jining, Shandong Provice. I graduated from Henan University of Technology in 2024 with a major in Chemical Engineering and Technology. I am honored to join Professor Sun's research group and learn and progress together with the group members. My motto is "No steps can lead to a thousand miles, no small streams can form the sea."（不积跬步无以至千里，不积小流无以成江海。）
