1996, Dongguan.
23-Year-old Li Chen was kicked out of his home by his adoptive parents, leaving only the words "You are not our son" and a photo of a strange woman.
The woman in the photo is called Sister Yan, and no one in Dongguan dares to touch a hair on her head.
Li Chen came to see her, but Sister Yan told him to get lost.
Li Chen refused to leave.
Until Li Chen pulled out the half piece of jade pendant around his neck.
She also had half a piece. But when the two pieces are put together, what they spell out is not a blood relationship, but a line of words carved with life, a ship sunk at the bottom of the canal.
