"Yam powder? What kind of yam powder?" Wan Wen asked in confusion.
The little girl walked to the box near the bed, opened it, and took out something wrapped in a red plastic bag.
Wan Wen placed the things that the little girl found on the table and opened the red plastic bag. It revealed an iron can with the words "yam powder" printed on it.
The little girl tugged at the table and looked up at Ye Ling and her mother. She said softly, "Uncle brought this back. He said it's a tonic. Grandma was reluctant to drink it at first, but Uncle said it would expire if she didn't drink it. That's why Grandma drinks a spoonful every morning. Grandma gave it to me before, but I thought it tasted awful, so I didn't drink it."
When Wan Wen and her husband were busy, they would send the little girl to the old lady to take care of her. That was why the little girl knew that the old lady would drink yam powder every morning.
