The day my grandfather died, it rained heavily. During the burial, there was a sudden knocking sound in the coffin.
I am the last generation of Chen family to keep the tomb. The ancestral precepts say: Don't enter when the mountains are closed, don't go deep into the mountains, and don't look back when you are deep into the mountains. But there is a door engraved on the bronze box left by grandpa - it is the Tongzu Cave that opens every sixty years.
There is something in the hole. Grandpa searched all his life and finally appeared in the river wearing a shroud.
In the hospital, the man in black looked at the copper ring on my hand and smiled: "You are finally here. I have been waiting for sixty years."
He said that there was more than just a key in the Tongzu Cave. And the person I'm waiting for.
