Three men prominent in these groups were arrested, including Sian NLVC leader Yü Chih-yuan. In addition, a warrant was circulated for Li Lien-pi, director of the NLVC Northwest Bureau, who happened to be out of town; he was picked up in Sanyuan County in July. With the apprehension of still another young man, the incarcerated leaders became known as the “Five Youths of Sian,” and a movement was undertaken to secure their release.
