A mother from eastern China has transformed the simple cardboard boxes into a police car costume for her son's kindergarten assignment.

The impressive video was filmed in the city of Qingdao in Shandong Province on December 6.

Tasked with creating eco-friendly clothing for a themed activity at school, this inventive mother decided to cater to her son's love for cars.

Drawing inspiration from online tutorials, she spent about five to six hours meticulously crafting a "car costume" that ingeniously morphs into a police car.
