According to Chinese news outlet Morning Post, the lights at the concert venue went out soon after the concert began, leaving thousands of fans waiting in the dark for more than 30 minutes. The same issue arose again with another power outage during the concert, leading to even more disruptions. 

In addition to the technical issues, fans were upset that they were only able to see 6 of the members on stage, due Rap Monster's unfortunate health conditions. 

Furthermore, reports stated that the event ended earlier than scheduled with BTS only performing 15 songs, while in Nanjing, the boys performed a total of 26 songs.

Despite the circumstances, including Rap Monster's heartfelt apology and other uncontrollable situations, fans express great disappointment with the words, "It was the last concert in China this year. They sang less songs than originally announced, and there were also multiple technical issues. We can't help but be disappointed."
