Nine-year-old Du Yihe silently prayed for his sick grandma to recover soon before going to bed. After praying for many days, he began to have trouble sleeping at night.
Unable to sleep, he sneaked out of the house and met a strange sleepy grandfather.
Grandpa Sleepy told him that there were many children in this city who could not sleep just like Du Yihe.
Purpose: To guide children to have a good understanding of all aspects of the city
