Over 70 years ago, more than 2 million people from various provinces of mainland China went to Taiwan, including nearly 600,000 soldiers. These veterans were separated from their families for half a century, yet their belief in returning home never faded. After two years of searching, interviews, and on-site filming, the documentary film focuses on six Taiwanese veterans with different origins, backgrounds, and identities, using real footage to capture the heartfelt voices of the Taiwanese people. Bearing the pain of a lifetime, they held onto the memory of their blood ties with mainland China, courageously and resolutely declaring, "I want to return to the mainland."
