Don't know the date on this clip, which is from a Taiwanese film set during the Sino-Japanese War of 1937-45(am judging by the uniforms worn by the characters in the clip), but suspect that it's probably from either the late '80's or early '90's, judging by the film stock.
Incidentally, the bugle tune being played in the clip is the Nationalist Chinese and Taiwanese flag raising song.
Some of you may also notice that the uniforms, and most especially the helmets, worn by some of the characters are of German design.
That's no accident, as between the early 1930's through about 1945, some units of the Chinese Nationalist army, especially the elite bodyguard troops assigned to protect Chiang Kai-Shek, were German-equipped, and this included the distinctive "coal-scuttle" steel helmets made famous during the First and Second World Wars.
However, given the disparity between various Central Government and Chinese regional armies during that period, some units wore British Mark I, or "soup-plate" helmets, others the old French Adrian 1916 helmets, others still the American Model 1942 "steel pot" helmet, and the vast majority had no steel helmets of any sort at all.
Be seeing you.
