Stand up with Chopsticks and Ask the Ghost, the Murderer I Know

During the summer vacation when I was nineteen years old, I saw with my own eyes ten blue and purple finger marks appearing out of thin air on my grandfather's neck. Later, I don't know why it became eleven. When Grandpa stood up three chopsticks to ask the ghost, at the moment when the chopsticks stood upright, someone else's voice came out of Tai Nai's mouth, repeating only one sentence: "Sun Changyou filled the well." I unearthed a bronze medal with the name of someone I knew engraved on it. Later, an owl fell on the old locust tree at Sun Changyou's house before it got dark. There are some things that you can ask with chopsticks, but you may not be able to give them away.
