Passage: At 04:36 on 25 August, a fire broke out in a kitchen of a karaoke bar on the hotel’s second floor. Many of the guests, mostly Chinese tourists staying for the 2018 Harbin International Marathon, were asleep. The fire itself spread over 400 square metres (4,300 sq ft) along the second through fourth floors and first floor main hall. Smoke from combustibles in the kitchen and karaoke bar spread up the stairways and air systems into the hallways, requiring firefighters to evacuate more than 80 guests with at least 20 needing rescue. A survivor of the fire told reporters "I didn't hear any smoke alarm until after the fire was extinguished ... There was heavy smoke in the corridor and no indicator lights pointing to the exit."At 07:50 the fire was considered extinguished, and fire officials discovered 18 fatalities inside the resort with one more fatality at the hospital. The death toll rose to 20 a day later, when investigators found one last body under the burned debris. The Beijing Jiufangyuyue Commercial and Trading Co confirmed in the days after the fire that all of the deceased victims were members of a 10-day trip through their company, aged 59 to 85.
