Because I don't know if India has ever filmed a war film between China and India. However, if you are asking for the name of an existing movie or TV series, I suggest you check the reviews of the movie or TV series or search for relevant information on the Internet to get a more accurate answer.
Pihu is indeed a real story. The events and situations depicted in it have roots in actual occurrences, making it quite impactful. The filmmakers likely took some creative liberties for cinematic purposes, but the core essence remains true to reality.
Well, without more context, it's difficult to pinpoint exactly. It might be a movie that delves into a tale of animosity. Maybe it could be about different groups in India having conflicts, like caste-based hatred or regional rivalries.
