[Cute baby + national cooperation + searching for the remains of heroes + unit tear-jerking + full network protection + life experience redemption]
Four-year-old Xiao Suisui has a secret.
When she touches the old things left by the martyrs, she can hear a small "echo" hidden by the years.
A rusty button allowed her to find a young warrior who had been sleeping for eighty years in a barren mountain; an unsent letter from home allowed the white-haired old man to finally wait until his brother came home; and half a longevity lock led to a watch that spanned four generations.
Facing the camera for the first time, Suisui hugged Xiao Honghua tightly and said in a sweet voice: "It's not that no one wants Grandpa Hero, it's just that the way home is too long."
Overnight, the entire network burst into tears.
Later, the national special team for finding relatives of heroes and martyrs officially held her little hand.
From snowy mountains to islands, from dense forests to exotic cemeteries, every year we listen to old things, identify echoes, look for clues, expert research, police escort, and DNA technology make all the unknown names shine again.
But no one knows that Suisui is trying his best to help others go home in order to find his missing mother.
Until a familiar voice came from the last old thing——
"Suisui, if mom doesn't come back, please take your place and bring the last hero home."
