According to local media in Vietnam, Chanyeol and others were reported to have entered Vietnam Hanoi Noibai Airport on the night of the 10th. EXO was scheduled to participate in the performance of Hanoi, a 2020 K-pop super concert, scheduled to be held at Hanoi Midin National Stadium on the night of the 11th.
However, problems arose when passport photos such as Chanyeol, taken by an Airport employee at the time, spread through local social media. EXO fans strongly opposed Airport employees and posted a series of articles demanding measures to prevent recurrence. “I sent it to Friend, an EXO fan, but I didn’t think it would spread like this,” said an Airport employee who leaked the photo on his Facebook account. “I sincerely apologize to EXO fans,” he said.
Airport staff "transmit to EXO fan Friend, sincere apology"
