Jin Changning remembered this very clearly.
That day, he was tired from playing outside and wanted to look for his mother. There was no one downstairs, so he ran upstairs.
He thought that his mother might be playing hide-and-seek with him, so when he went upstairs, he clung to the railing and walked quietly.
The door upstairs was ajar. When he pushed it open, he saw his father sitting by the bed and his mother kneeling on the bed. She was holding her sleeping sister in her arms and gently patting her.
He didn't call out and quietly walked over.
The bed was covered with a strange and ancient leather object. There were some curves drawn on it, and some strange words that people could not understand were written on it.
His parents were so engrossed in watching that they didn't notice him and were only discussing.
