With the ability to run above 4~GeV, the BESIII experiment located in the Beijing Electron Positron Collider (BEPCII), has becoming a pioneer in searching and studying charmoniumlike states (XYZ particles). In 2013, BESIII Collaboration discovered a charged charmoniumlike state Zc(3900), which is confirmed immediately experimentally, and provides the best candidate for a four quark state by now. Continuous studies by BESIII Collaboration show new decay behavior of Zc(3900), and there are possible partner particle Zc(4020)/Zc(4025) existing. By scanning above 4~GeV, BESIII also reveals the potential connection between Y(4260) and X(3872) for the first time, which may help us understand XYZ particles in a new sight.
