A number of witnesses claimed that the park experienced an unanticipated power outage that caused all roller coasters to remain suspended for more than 20 minutes.

According to a representative of the Qinhuangdao City Culture and Tourism Bureau, power outages are unusual, and the management of the theme park is investigating the cause. Once the backup power was activated, the train could start running again.
