A lamp's oil running out was just a normal occurrence, but it became the cause for a lot of suspicion as well as a lot of arguments between a couple of servants.
"Someone living in another courtyard must have needed more oil so they took the oil here away."
"Why would they take just the oil? Wouldn't it be easier to just take the lamp?"
"They're all weird people and their thoughts are… "
"Shh… Do you want to die?"
"Look, do you see this? There are traces of smoke on the wall. Someone must have lit the lamp in this room to read the patterns."
"Impossible. I don't know anything about kung fu, but I still know these patterns are defective. If I were in charge, I would have had all of them removed."
"Should we report this then?"
"I think so."
