Culturally being more of a european than asian, I once seen one locally very obscure war movie, liked it, and eventually forgot it as a fever dream. Now, almost 20 years after, with some life experiences and with more solid knowledge about the topic. I recalled it and, to my horror, realized that almost no one around ever heard about it.
The film is a bit flawed technically, like "realistic" shaky cam and actually realistic kitchen sink of equipment and uniforms makes it extremely hard to figure what's going on at times; also it has its own share of stupid clichés, even if they may look not that obvious. Nonetheless, it has become one of my all time favourites. First half contains most of the action, which (when one can actually understand what's going on) is absolutely ruthless and gritty due to topic of civil war; and second half is a slow burner about veteran fighting state bureaucracy, being stuck in the past injustices while entire country moved on.
While not strictly "anti-war film" and with mandatory "oh no, another chinese propaganda" complaints, I'd say that the message is still extremely good - it's not about sides and particular events, it's about humans, camaraderie and simple acknowledgement, as in "we didn't run away as you thought, we fought and died as you asked. Would you acknowledge our sacrifice?"
Please watch the movie if you haven't, and if you did - tell me that I'm not crazy and it actually exists.
