The move to revise the Civil Code to lower the age of adulthood to 18 from 20 is raising concerns that teenagers might fall victim to fraudsters.

Under current law, parents can cancel contracts signed by their children if the deals were sealed without their consent. But once the law is revised, this would no longer apply to 18- and 19-year-olds.

To reduce the risks of deception, the central and local governments have been beefing up consumer education for youths, but its effectiveness remains unclear.
