The pillar light box in Area C is located in the core passage of the entrance and exit station (the specific location may be associated with the east/west plaza), guarding the pedestrian route. The light box adopts a multi-faceted three-dimensional design (commonly 4 sides/column), with a horizontal field of view covering up to 360°, and a height that accurately matches the 1.2-2.5 meter passenger head-up band to form a visual surround without dead ends
The subway environment forces passengers to actively look around for information, and the depth of advertising absorption is about 4 times that of terrestrial media. Combined with the high-speed rail hub's average daily passenger flow of more than 250,000, the peak of subway passenger flow, such as 415,800 on May Day in 2025, the mandatory exposure in a single day can exceed 150,000 times
As a scarce hard and wide carrier in the channel, there is no digital screen interference to ensure the complete transmission of brand information. The continuous pillar matrix constitutes a "visual firewall" to strengthen the brand memory reflection
Hengyang Cultural Tourism combined with AR interaction to undertake high-speed rail tourists, and the Spicy Prince realized the explosion of brand voice through the pillar matrix at Wuyi Square Station, verifying the value of regional precision marketing
With "hub traffic× forced reach× intelligent interaction" as its core competitiveness, the Baozhu Light Box in Area C is a strategic medium for brands to seize high-net-worth individuals (40% of business customers and 35% of tourists) in Central China. It should be noted that the actual location needs to be subject to the official division, and there are differentiated layout characteristics of the light box resources in the east and west squares
Professionally operated by Hunan Tianwen Metro Media, it provides one-stop service from design to launch. The Changsha high-speed rail hub will have a passenger flow of more than 100 million passengers in 2024, and the average daily passenger flow of the subway is expected to reach 4 million in 2028
The regular price is about 468,000 yuan/set/4 weeks, referring to the 5-column set in Area B, which is lower than the 300,000-600,000 yuan/month cost of high-speed rail LED screen. An automobile brand has launched 1.5 million exposures in a single day, and cultural tourism projects (such as Zhangjiajie) have successfully established the "totem pole of consumer faith" effect through baozhu
