By 25 July, Japanese reinforcements in the form of the IJA 20th Division arrived and fighting reerupted first at Langfang, a city on the railroad between Beiping and Tianjin, between companies of Japanese and Chinese troops. A second clash occurred on 26 July, when a Japanese brigade attempted to force its way through Guanghuamen Gate in Beiping to "protect Japanese nationals". The same day Japanese planes bombed Langfang.
