T-26 tank in KMT service.some question.

during the 30's China purchased T-26 tank from soviet,this was at that time best tank of that era, her 45mm tank gun could easily destroy japanese tankette.(during the invasion of the philippine,some japanese tankette were destroyed by stuart 37mm tank gun).
is there any record of tank to tank engagement between the chinese force and the japanese?

China's T-26 saw battle in the Battle of Lanfeng, it also saw battle where it inflicted defeat to the Japanese Army at the Battle of Kunlun Pass.

The only armored division China had was the 200th and it had some notable encounters with the IJA
