Mayday's Back to That Day 25th Anniversary World Tour Taichung stop will begin on December 27 at the Intercontinental Baseball Stadium. To welcome the concert, the Taichung City Government has launched five limited-time “fan-friendly photo spots,” connecting Taichung Park, Calligraphy Greenway, the MRT Green Line, the Cultural Heritage Park, and themed city buses, inviting fans and visitors to explore the city at year's end.

Among the highlights are the five giant inflatable installations titled Because of You, Five Spheres, symbolizing the band members and making their debut in Taiwan. This year, the installations are adorned with Christmas decorations and placed on Sun Moon Lake in Taichung Park. During the day, visitors can stroll around the lake for photos, while at night the illuminated spheres reflect on the water, creating a festive atmosphere. Large Mayday figures are also displayed at Calligraphy Greenway, complementing the National Taichung Theater and showcasing the city's urban character.

The MRT Green Line has also become a key promotional feature, with Songzhu Station transformed into a Mayday-themed station featuring concert visuals throughout the space. Additional themed designs can be found at Taichung HSR Station, City Hall Station, and Wenxin Chongde Station, encouraging fans to collect memories across the city.

In addition, the MAYDAYLAND in Taichung exhibition will run from December 19 to January 4 at the Cultural Heritage Park, while 14 city bus routes feature special Mayday-themed designs, bringing music elements into everyday city life. The city government noted that these limited installations will remain through early next year, inviting the public to enjoy Taichung via walking and public transportation.
