Stage car (also known as mobile stage car or performance car) is a special vehicle based on the modified chassis of Class II cars, equipped with hydraulic automatic unfolding system and professional performance equipment (lighting/sound/background). It is specifically used as a mobile performance platform for cultural performances, cultural trips to rural areas, commercial activities, celebration events, and emergency publicity. Its core positioning is a "mobile and fast performing arts space", with the core advantage of "completing construction/evacuation within 30 minutes", without the need for fixed venues and complex construction processes, achieving "performance upon arrival and departure upon completion". It is a flexible carrier for cultural dissemination and commercial marketing, widely serving cultural and tourism departments, performing arts companies, and corporate brands.
