In 2011, the firstDwarf nova[18-19](The first dwarf nova discovered by domestic astronomers).
In 2015, the first comet C/2015 F5 SWAN Xingming was discovered[20](Therefore, 2015Eg Wilson AwardWinner)[4][8]；Senior administrator of PSP public supernova search project[21]。
In 2017, the first planetary nebula Sufe 1 was discovered[12]。
In 2020, publish the first astronomical paper[22]；Found 2 new binary stars[22]；Signed 2 SCI papers[23-24]；Joined the Chinese Astronomical Society[5]Zhejiang Astronomical Society；Lead the formation of VSSP Variable Star Search Program[31]。
In 2021, asteroid 546756 was named after him[29]；Name (546049) Zhu Jinxing;The discovery of two strong gravitational lenses (first discovered by Chinese astronomers).
2022: Name (616689) Yihangyiyang as one star;Led the establishment of the XESP exoplanet search project[32]；Discovery of the first exoplanetTOI-4562 b(First discovery by Chinese astronomy enthusiasts);Discovery of the first quasi nova, active galactic nucleus, and initial stellar body (first discovery by Chinese astronomers);Signed several astronomical journal papers[33]。
2023: discovery of the first near Earth asteroid (first discovery by Chinese astronomers);Engaged as the instructor of Wenzhou Youth Astronomy Association;Served as the director of the International Astronomical Search Cooperation Organization (IASC) - China Astronomer Asteroid Search Activity;Signed several astronomical journal papers[33]。[I]
