Abstract
Since the first XYZ particle X(3872) was observed in 2003, many exotic states have been found by spectroscopy studies in beauty and charm sectors. In this paper, the latest XYZ results obtained by BESIII are reviewed, mainly including X(3872), Y(4260), Y(4660), Zc (3900) and Zc (4020). The spin parties of Zc(3900) have been studied. The comparison between different final states in Y states which are helpful to understand the nature of XYZ particles has been done.
