何応欽
On 29 May 1935, General Takashi Sakai, Chief of Staff of the Japanese China Garrison Army based in Tianjin, acting on the pretext that two pro-Japanese heads of a local news service had been assassinated, raised a formal protest to Kuomintang General He Yingqin, Acting Chairman of the Peiping National Military Council. The Japanese Army demanded the dismissal of Hebei Provincial Chairman General Yu Xuezhong from his posts and for the Kuomintang to cease all political activities in Hebei, including the cities of Tianjin and Beijing (Peiping).
