I Dug up a Coffin I Shouldn't Have Dug

I am a technician at the Archaeological Institute and have been working there for eight years. Last month, a Song Dynasty tomb was discovered in eastern Henan. Seven copper coins were nailed to the coffin lid. The placement of copper coins is the Big Dipper. The captain said it was for tombs. I couldn't help myself and took a piece of the copper coin. That night, seven people in our team had the same dream.
