Yun Xiaoxiao began explaining to them, "Although they are roots, they belong to vine plants, and there is starch inside the roots, which makes them edible. Just tell Er Dan to dig up the roots, wash and sun-dry them, and later on, I'll show him how to prepare them to eat."
This suddenly shocked the two little ones.
So, some roots really are edible.
"Mom, did you read about it in a book?"
Yun Xiaoxiao nodded her head, "Yes, I read it in a book, so we need to read more books to understand many things, such as why does it rain? Why is there thunder? Why do fish swim in the water instead of on the shore? And so on. We can find the answers to all these questions."
"Why does it rain? Isn't it because if the lord in the sky wants it to rain, it rains?" Da Bao knew this because he had heard other children say that the lord in the sky makes it rain whenever he wants.
Yun Xiaoxiao patted Da Bao's head and explained, "Before it rains, don't you see the sky fill with dark clouds?"
