On May 25, 2022, after "only hearing the sound of the stairs" for a long time, Kuomintang star Jiang Wanan finally officially announced that he accepted the Kuomintang's nomination to run for mayor of Taipei. Earlier, Wu Yinong, who had competed against him for the legislature seat and lost two years ago, also announced that he would not be re-elected as the chairman of the Taipei City Party Department of the DPP, and would "stand up where he fell and where he fell". The legislature vacancy left by Jiang Wanan after the election of the mayor.
The advance and retreat of the two not only banner design attracted the attention of Taiwanese politics, but also attracted the attention of fans. In the group of "Jiang Wan'an Local Mother Support Association", photos of Jiang Wan'an's handsome smile at the press conference announcing his candidacy were circulated, "So handsome!" "Look at how gentle he is!" Same!" However, on the other side, in a club composed of iron fans of Wu Yinong, they only coldly teased Jiang Wanan that "the muscleless triangular eyes are coming." "Skinny monkey, where is he handsome? "Yinong is the highest! Come on, Yinong!" For a while, the supporters on both sides were pulled back to the lively time of 2020, the "Double Handsome Showdown" in this constituency.
In the previous (2020) year, the Zhongshan and Beisongshan constituencies, known as "the most handsome constituencies in Taiwan", were lively and noisy throughout the country due to the participation of Jiang Wanan, the fourth generation of the Jiang family, and Wu Yinong, the son of the well-known scholar Wu Naide. Jiang Wanan is 176 cm tall, with a gentle and clean appearance, gentle and polite speech, and has the status of an American lawyer. When he stepped into the political arena in early 2016, he attracted many women's votes.
