Min-Zhe　bridge　in　Fu-Jian　and　Zhe-Jiang　Provinces　of　China　is　a　unique　type　of　woven　wooden　arch　bridge　with　important　cultural　heritage　values　in　both　tangible　and　intangible　fields.　Reconstruction　(including　in-situ　rebuilding　and　relocation)　is　a　traditional　approach　to　extend　the　bridge＇s　lifespan,　which　has　been　passed　on　and　lasts　till　now.　Today＇s　reconstruction　practice　and　its　legitimation　on　intervening　in　the　Min-Zhe　bridge　as　both　tangible　and　intangible　heritage　is　discussed　in　this　paper　under　the　modern　conservation　context.　Firstly,　the　reconstruction　activities　since　its　＇discovery＇　in　1980　are　investigated　through　general　information　and　case　study.　Then,　the　legitimation　issues　are　discussed　according　to　the　criteria　of　the　authenticity　text　for　World　Heritage　bridges　and　the　criteria　of　continuity　for　living　heritage.　Finally,　suggestions　on　protecting　the　continuity　of　the　building　tradition　and　ensuring　the　reliability　of　the　continuous　production　in　the　future　are　proposed.
