This　study　investigates　the　social　processes　of　place-making,　sense　of　place,　and　place　branding　within　the　context　of　private　art　museums　in　Eastern　China,　highlighting　their　role　in　fostering　social　interaction　and　contributing　to　urban　sustainability.　By　examining　the　relationship　between　exhibition　design,　interactive　features,　and　audience　engagement,　the　research　demonstrates　how　these　museums　act　as　cultural　spaces　that　not　only　display　art　but　also　facilitate　dialog,　community　building,　and　cultural　reflection.　Using　a　mixed　methods　approach,　including　surveys　and　case　studies,　this　study　explores　how　private　art　museums　employ　place-making　strategies　to　create　immersive　environments　that　blur　the　boundaries　between　art,　architecture,　and　visitors.　These　museums　enhance　emotional　engagement,　promote　cultural　understanding,　and　support　sustainable　cultural　identities　within　urban　spaces.　The　findings　reveal　that　through　thoughtful　design　and　community-centered　programming,　private　art　museums　in　Eastern　China　contribute　to　the　social　sustainability　of　urban　areas　by　creating　spaces　that　are　both　culturally　and　emotionally　resonant.　Furthermore,　the　place　branding　of　these　museums　positions　them　as　dynamic　cultural　landmarks,　reinforcing　their　significance　in　the　urban　landscape　and　fostering　ongoing　social　interaction.
