A　threshold　quantum　secret　sharing　(TQSS)　scheme　between　multi-party　and　multi-party　was　proposed　using　a　sequence　of　single　photons,　which　is　useful　and　efficient　when　the　parties　of　communication　are　not　all　present.　We　described　the　process　of　this　TQSS　scheme　and　discussed　its　security.　It　was　shown　that　entanglement　is　not　necessary　for　quantum　secret　sharing.　Moreover,　the　theoretic　efficiency　was　improved　to　approach　100%　as　almost　all　the　instances　can　be　used　for　generating　the　private　key,　and　each　photon　can　carry　one　bit　of　information.　This　protocol　is　feasible　with　the　present-day　technique.
