Hu Zhenjiang, deputy director of the Civil Aviation Administration of China, said search and rescue teams have identified 120 victims of the crash, according to Chinese state media.
No explosives were found at the crash site, according to the head of the Fire and Rescue brigade.
The aircraft's second black box contains flight data recordings, according to the state newspaper China Daily.
Search teams located an emergency location transmitter close to where the second black box was installed in the plane, which may mean they are closer to finding the flight data recordings.
Search and rescue teams found the plane's other black box, which was severely damaged, and sent it to experts in Beijing.
China Eastern Airlines Flight MU5735 suddenly plummeted into a near vertical drop after an hour into its flight from Kunming to Guangzhou on Monday. Aviation experts are puzzled by the fact that the Boeing plane dropped almost 22,000 feet in just over a minute before it crashed. Search and rescue crews have been combing through the debris for days, and have located identification cards, wallet, and bags from the 123 passengers and nine crew members aboard. China Eastern has temporarily grounded its fleet of Boeing planes to complete a large-scale safety inspection, though the model has been involved in fatal crashes in the past.
Boeing admitted full responsibility for the crash of the newest model of the aircraft in Ethiopia in 2019. The planes were killed in two crashes. A faulty new flight control system is to blame.

State Broadcaster says no survivors were found in the crash of the plane.
