I’m a graduate student in Xi’an Jiaotong University, majoring in computer science. It’s my great honor to be mentored by Prof.Qin. Meanwhile, I’m also so lucky to study under the guidance of Professor Jun Liu.

My research interests include LLM reasoning, LLM (GUI) agent, etc. Please refer to Google Scholar for more information.
