With the information of the hadronic decays of J/psi and psi(3686), it is found that a large branching fraction, up to 13% of the total psi(3770) decays may go to charmless final states. The experimental search for these decays is also discussed.8 pages, 3 figuresHigh Energy Physics - Phenomenologytext
