中国物理学会高能物理分会第十三届全国粒子物理学术会议（2021）

With the accumulation of data samples above 4 GeV in recent years, BESIII collaboration has systematically investigated possible conventional charmonia and Y states, as well as their decay channels. Through a series of process cross section measurements, including open charm and hidden charm channels, BESIII provided a lot of information on the vector states. In this talk, we would like to show some results on the vector states studied at BESIII in recent years.
