On 25 October 1997, a mass tug-of-war contest was held at a park along the Keelung River in Taipei in celebration of Retrocession Day (the 52nd anniversary of the end of the Japanese colonial rule in Taiwan). Over 1,600 participants joined in the contest, exerting an estimated 80,000 kg or more of force on a 5-cm nylon rope that could bear a force of about 26,000 kg at most.

Within seconds the rope snapped, severing the left arms of two men, Yang Chiung-ming and Chen Ming-kuo, below the shoulder.

The victims were taken to Mackay Memorial Hospital and underwent seven hours of microsurgery to reattach their arms:

A similar but less severe set of injuries occurred during a February 2013 incident in Southern California, when two students at South El Monte High School lost fingers during a tug-of-war contest:
