Wow how strange!
I watched this movie in TV also when I was around 6yrs old in Philippines. It was 1977 when it was shown I believe. I cried like a baby, real loud when the train left and the movie ended with the field of sunflowers. From time to time, years later when I was in elementary school, then through highschool and now (I'm in my 30s), my mother would still mention about how I cried during the ending of "SunFlower" as a little boy.
I saw the ending scene again just recently and it brought back feelings I had when I was a kid, this time though I only had tears in my eyes. I guess I can control my emotions better now. Nevertheless, the movie is still effective. And yes, I remember those really sad scenes where there were dead soldiers lying on the snow. I also remember when her husband accidentally swallowed her earings in the beginning. This is memories remembered 30yrs ago as a 6yr old boy about a movie.
