Taiwanese band Mayday completed 12 concerts at Beijing National Stadium from April 30 to May 18, 2026, as part of their "5525+2 Back to That Day Tour" [1, 2]. The performances brought the band's total at the venue to 55, a record for any artist at the stadium [3, 4, 5].

On May 19, lead vocalist Ashin (Chen Hsin-hung) posted a series of social media selfies taken during a late-night walk through Beijing's hutong alleyways. One photo showed him posing in front of a men's public toilet in a residential area [1, 3, 2]. Fans quickly identified the toilet's location and began flocking there to take their own photos mimicking Ashin’s pose [1, 6, 2, 7].

The sudden influx of fans caused long queues and crowds around the toilet, which serves many households lacking private facilities. Residents reported noise pollution, blocked access, and traffic congestion resulting from the gatherings [1, 6, 8, 2, 7]. A local resident said, "This is not a tourist site; it’s a place people use daily. Fans lining up and taking photos kept residents from using the toilet properly" [6].

Some fans even entered the toilet, placed Mayday member names on individual stalls, photographed inside, and shared the images online. This behavior drew criticism for invading privacy and disrespecting local users. Another resident stated, "Posting pictures inside the toilet with band members’ names is not only foolish but exposes a private environment. It’s inappropriate and disrespectful" [8].

Journalist and columnist 蓝靖仪 commented on the incident: "Fans' enthusiasm is understandable but they must maintain limits and not disrupt public order" [9].

On May 23, Ashin issued a public apology on social media. He expressed amazement at fans' ability to find the exact toilet and apologized for the trouble caused to residents, urging fans to "check in sensibly and kindly support local residents and businesses" [1, 3, 6, 2, 7, 5]. He also deleted the original toilet selfie from most social media accounts after the incident [1, 3, 4, 5].

The incident prompted mixed reactions. While many fans praised Ashin's apology and called for rational enthusiasm, local residents voiced strong annoyance over the disruption and inconsiderate fan actions [1, 6, 9, 2, 4]. Residents emphasized that the public toilet is an essential daily facility for the neighborhood and should not become a tourist attraction [6, 8, 2, 7].

Mayday’s tour now moves beyond Beijing, with no public reports yet indicating similar incidents elsewhere.
