  The BESIII Experiment at the Beijing Electron Positron Collider (BEPCII)
collected large data samples for electron-positron collisions with
center-of-mass above 4 GeV. The analysis of these samples has resulted in a
number of surprising discoveries, such as the discoveries of the electrically
charged $\mathrm{Z_c}$ structures, which, if resonant, cannot be accommodated
in the traditional charm quark and anti-charm quark picture of charmonium. In
this talk, we will review the current status of the analyses of the exotic
states, as well as a number of other interesting features in the new BESIII
data samples.
