We observe an obviously anomalous line shape of the cross sections for e{sup +}e{sup -{yields}} hadrons and e{sup +}e{sup -{yields}}DD-bar in the energy region between 3.700 and 3.872 GeV. They are inconsistent with the explanation for only one simple {psi}(3770) resonance in the range from 3.70 to 3.87 GeV, which indicates that either there is likely a new structure in addition to the {psi}(3770) resonance around 3.773 GeV, or there are some physics effects reflecting the DD-bar production dynamics. With the data taken around 3.097, 3.686 and 3.770 GeV, we measure the inclusive K{sup 0}/K*{sup 0} decay branching fractions of the J/{psi}, {psi}(3686) and {psi}(3770) resonances for the first time.
