Were there any sword fights between the Japanese and the Chinese soldiers during the 2nd Sino-Japanese War?

Hello Indy, I was a viewer since the Great War Channel. I’m asking you this question because my grandfather (my dad’s side) was a Kuomintang soldier that took part in the defense of Hong Kong. My mom said that he was part of the Dadao regiment where these soldiers were simply given a dadao and a sidearm.
