就我而言，我一无所知，但满眼的繁星让我入梦。
For my part I know nothing with any certainty, but the sight of the stars makes me dream.

Research Interests
As an early-career researcher, I have great enthusiasm and interest in various fields and am willing to be exposed to new knowledge and challenges.
I am currently focus on 🤖large language models (LLMs), with a particular interest in enhancing the intelligence of models through techniques such as knowledge distillation, reinforcement learning, self-learning and evolution.
I am also interested in 🌐downstream applications of LLMs, including prompt engineering, RAG and agent systems.
