Unexpectedly, Xibao didn't rush to the door. Instead, he turned towards Grandfather Lu and said, "Grandpa, cake!"
Grandfather Lu immediately got it, "You want to buy a cake ,right?"
"Hmm!" the voice from under the scarf answered were particularly loud and clear.
"Let's go, Grandpa will buy you a cake!"
Grandfather Lu immediately took money and went out with them. Following Xibao's directions, he bought a very expensive cream cake, packed it in a paper box, tied it firmly, and handed it to Zhonghua, "Zhonghua, your younger brother is small and doesn't have the strength. You carry it for him. When you've finished playing, Grandma will open the box and share the cake."
"Thank you, Grandpa Lu!" Zhonghua answered politely.
Grandfather Lu patted his head, "Well then, go and play with your younger brother."
