In　this　paper　we　investigate　the　properties　of　tunneling　spectrum　from　weakly　isolated　horizon　(WIH)-a　locally　defined　black　hole.　We　find　that　there　exist　correlations　among　Hawking　radiations　from　a　WIH,　information　can　be　carried　out　by　such　correlations,　and　the　radiation　is　an　entropy　conservation　process.　Through　revisiting　the　calculation　of　the　tunneling　spectrum　from　a　WIH,　we　find　that　Zhang　et　al.＇s　(Ann　Phys　326:　350,　2011)　requirement　that　radiated　particles　have　the　same　angular　momenta　of　a　unit　mass　as　that　of　the　black　hole　is　unnecessary,　and　the　energy　and　angular　momenta　of　the　emitted　particles　are　very　arbitrary,　restricted　only　by　keeping　the　cosmic　censorship　hypothesis　of　black　holes.　So　we　resolve　the　information　loss　paradox　based　on　the　method　of　Zhang　et　al.　(Phys　Lett　B　675:　98,　2009;　Ann　Phys　326:　350,　2011;　Int　J　Mod　Phys　D　22:　1341014,　2013)　in　a　general　case.
