Satisfying footage shows automatic machines completing various tasks on production lines at factories in China.

The robotics have been assisting workers by sewing elastic bands into pants, wrapping labels onto aluminium cans, boxing fruit juices, and mounting car tyres with remarkable precision in Jiangsu.

Footage shows a worker threading elastic into pants using a bendable wire, while labels are added to cans and bottles sorted and packed by other machines on December 26.

At a separate facility, cut fish are efficiently sorted by size, and hydraulic presses shape metals into chains and other construction materials.

While technological advancements continue to revolutionise factories, concerns remain about the impact on human employment.

One worker at the plant said: 'Technology changes lives, but also takes jobs. It seems like only haircuts still need human hands.'

China has a large workforce with relatively low labour costs and a well-established manufacturing industry.
