Xiao Chang didn't understand what they were discussing, but when he heard Na Na talk about the pastries and cookies, he said, "That's right, I asked you to share the cookies with everyone. Did you share them with everyone?"
"I... I did share them," Na Na chose to lie once more. "I handed out the cookies as soon as I left the house, you can ask the other servants if you don't believe me."
Zhuang Liu interjected, "How many cookies were there on that plate?"
Xiao Chang replied, "There were ten in total because a tray can fit twelve, and after messing up two, I kept them to figure out what went wrong, and gave the rest to Na Na."
"Interestingly, there were also ten cookies on that plate." Zhuang Liu had a very good memory. "The bottom layer had six, and the top layer four, making exactly ten cookies. I haven't finished them yet; they are still out in the yard. You can go check if those are the cookies you provided."
