Yin Xiyue officially entered the detention center on the 19th

South Korea's detained president, Yoon Seok-yeok, has become the first president in South Korea's constitutional history to be formally detained in a detention center as a sitting president after completing the relevant procedures such as taking photos of the suspects. Unlike when he was arrested, Yoon Seok-yeok, who is a suspect, needs to go through various procedures for admission, including changing his private clothes into prison clothes and holding a detention number plate to take photos of the suspects, confirming personal information, undergoing a detailed physical examination, and entering fingerprints. After completing various procedures, he has officially entered the detention center.
