After finishing their meal in the restaurant's private room, Zhang Qian called the server to tidy up the table, served the dessert, and closed the private room door. She then signaled Yang Zhuo to start his "show".
"Sister Qian Qian, we can start with a small Q&A game," taking a new deck of cards from his sister's bag, Yang Zhuo began shuffling them while talking, "Sister Qian Qian, you can ask me three detail questions about the surroundings or people from the moment we entered the restaurant until now. Any questions are fine. For example, you can ask how many floor tiles there are between the restaurant entrance and our private room, how many crystal balls hang from the chandelier in the main hall, the pattern and color of the curtains, and so on."
Zhang Qian found this interesting and asked after some thought, "How many water pots and cups are on the cabinet behind you?"
