The accident saw both the baby boy's heavily pregnant mother Wang Zhau, and his father Mao, hit by a truck as they were going to hospital on a motorcycle yesterday.
The baby was born in the impact of the collision. He was thrown out of the woman's belly and landed three meters away.
The baby is in critical condition.
"It is a miracle that the infant survived the gruesome road accident," Fang Mei, a pediatrician at Haicang Hospital.
