1. Strong academic background: Tsinghua University is one of the top higher education institutions in China, with world-class academic level and faculty. Tsinghua, a postdoctoral fellow, went out to prove that he had obtained a doctor's degree in this field, and conducted long-term research in Tsinghua University.

2. Rich research experience: Postdoctoral students are the further research and training after doctoral graduation, and usually need to complete their research work independently under the guidance of their tutors. Tsinghua's post-doctoral withdrawal means that he has accumulated a lot of research experience in this field and can complete scientific research projects independently.
