South Korean politics has a tradition of sending his predecessor to prison. Mr. Yoon has sent two former presidents to prison.
Yoon Seok-wook has more than 20 years of experience in the prosecution system and has personally sent former presidents Park Geun-hye and Lee Myung-bak to prison, so he was named an "anti-corruption fighter".
He came from Moon's opposition party and advocated the abolition of the "three noes policy" advocated during the Moon era, and not participating in the US missile defense system, not participating in the US-Japan-ROK military alliance, and not further deploying the THAAD anti-missile system.
Yin Xiyue highlighted the US-ROK alliance and took a tough attitude toward China.
One of his election claims was to attack feminism. He has made explicit statements such as "there is no structural gender discrimination in South Korea", and last month stressed the need to strengthen the "punishment for false accusations of sexual crimes" and promised to abolish the "Women's Family Department", an administrative department with feminist symbolism in South Korea, as soon as he took office. Many of his supporters in this vote are young men from South Korea.
In addition, during the presidential campaign, Yoon Seok-yue and his surroundings also had a number of scandals, including being exposed to superstition and "witchcraft".
