We propose a new semileptonic tag method to study the doubly Cabibbo-suppressed D decay in ψð3770Þ → D D reaction. Utilizing the dataset corresponding to an integrated luminosity of 2.93 fb −1 at a center-of-mass energy of 3.773 GeV collected by the BESIII detector, we determine the branching fraction a
