In this study, we investigate the discovery potential of double-charm tetraquarks $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ . We find that their production cross sections at the LHCb with $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ TeV reach $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ pb, which indicates that the LHCb has collected $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ such particles. Through the decay channels of $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ or $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ (if stable) or $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ (if unstable), it is highly expected that they get discovered at the LHCb in the near future. We also discuss the productions and decays of the double-charm tetraquarks at future Tera- $ T^{\{cc\}}_{[\bar{q}\bar{q}']} $ factories.
