In 2017, archaeologists began using historical files as reference and applied digital imaging technologies to determine the location of the wreckage. They removed thick layers of sand to expose part of the ship's hull.
Zhou Chunshui, who leads the project under the National Center of Underwater Cultural Heritage, revealed that the wreck was in "poor condition".
"The entire superstructure of the ship has disappeared," Zhou said. "The scattered discoveries are mainly of mechanical cabins and crew quarters below deck."
Japan salvaged some components of the Dingyuan in 1896 and built them into a house in Fukuoka.
Zhou said follow-up research of the wreck will continue next year to get more comprehensive information after additional portions of the ship are extracted from the seafloor.

The National Center of Underwater Cultural Heritage launched an archaeological program in 2014 to investigate the shipwrecks of the Beiyang Fleet. The Zhiyuan and the Jingyuan, two Chinese cruisers sunk in the Battle of the Yalu River on Sept 17, 1894, have been found off Liaoning province.
The two vessels were basically in good condition, according to Jiang Bo, an archaeologist at the center.
The Beiyang Fleet was hailed as the strongest in Asia on the eve of the First Sino-Japanese War and Liugong was its main hub. Nevertheless, the fleet was annihilated during the conflict.
This year marks the 125th anniversary of the outbreak of the Sino-Japanese War. Liugong Island, former office site of the Beiyang Fleet, has been developed into a "foundation for patriotic education" to remind young generations to learn from the bitter lessons of history.
