The people who accompany Youyou the most are his grandparents. Yo-yo's grandfather is a demobilized soldier, with a strong body and many comrades-in-arms, and he often contacts. After finishing his major, he was assigned to the Industrial and Commercial Bureau and then transferred to the urban management system.

He has hyperthyroidism and has been taking medicine. After Youyou fell ill, in order not to let his son and daughter-in-law delay their work, they took a long vacation with the unit to take care of Youyou's recovery.

Youyou's grandmother is a retired teacher in her village. She is dark and not tall. She is almost like Yo-Yo's mother. She is 1, more than 5 meters. She has a hunchback, walks slowly, has high blood pressure and is weak.

Yo-yo's parents:

Your mother graduated from normal school and is a primary school teacher in their village. She is about 30 years old. She is not tall, thin and small. She doesn't talk much and her voice is very low. I can't seem to hear her talking loudly. She just came over for a period of time during the holiday to accompany Youyou to recuperate and let Youyou's grandfather rest for a few days.

Youyou's father is generally short and introverted, and works in a private enterprise in the suburbs. He doesn't come here often. When he comes, he seldom plays yo-yo. He always sits alone and watches his mobile phone.
