The video recalls bitter memories of a similar tragedy of a toddler's death a year ago.
The recording was posted by a netizen named "Wang Yujing" on his Weibo account on Monday, showing a mother crying on the ground after seeing her son lying under the minibus.
About ten passersby witnessed the accident and several cars were traveling by at the time, but no one offered to help the mother.
"Eventually, the boy died because of serious injuries," the netizen wrote.
The video was forwarded more than 22,000 times within hours.
According to local police, the deceased boy, whose name is Yan Zhe, was five years old.
