In late April 1937, Zhang Yunyi was sent to Hong Kong to lead the south anti-Japanese national united front (). He collected donations in Hong Kong and Macao and persuaded Ye Ting to join the war against Japan. After the Marco Polo Bridge Incident, according to the instruction of the Central Committee of the Communist Party, Zhang Yunyi discussed with Li Zongren and Bai Chongxi in Guilin in hopes that Li and Bai would join the anti-Japanese national united front.
