She knelt in the bloody mud and put an automatic rifle with body temperature into the hands of the sixteen-year-old soldier.
Cheng Nian is an ordinary military museum docent. He talks about history to the old rifles behind the glass showcase every day until his voice becomes hoarse and his face bursts into tears.
She will never forget her grandfather's words before his death - "Nian Nian, at that time, we had three people with one gun."
An accident caused her to fall into the smoke of war in 1940. Her cell phone was still there but there was no signal.
But she discovered that as long as she opened the photos of weapons in the photo album of her mobile phone and traced the outlines with her fingers, those photos would "grow" out of the screen and turn into real modern weapons.
Type 95 rifle, body armor, first aid kit, thermal imaging camera...
She was like a person who sent a package from the future, handing over items that "impossible to exist" into the hands of the soldiers.
But every time a weapon is forged, a piece of her memory will disappear.
She began to forget what her parents looked like, her own name, and the way home.
She knew she would forget everything eventually.
But she said: "As long as they live, it doesn't matter if I forget."
