Since the first XYZ particle $X(3872)$ was observed in 2003, many exotic states have been found by spectroscopy studies in beauty and charm hadrons.
In this paper, the latest XYZ results are reviewed, mainly including $X(3872), X(3915), Y(4260), Y(4360), Y(4660), Z_c(3900), Z_c(4020)$ and $Z(4430)$.
The spin parties of X and Z particles have been studied, and the comparison between different final states in Y particles has been done, which are helpful to understand
the nature of XYZ particles.
