naval construction program, inspected the vessels following their arrival. The two ironclads were then commissioned into the Beiyang Fleet, which was based in Port Arthur. The ships steamed south to Shanghai for the winter of 1885–1886. In the 1880s, the Beiyang Fleet was occupied with an annual routine of winter training cruises to the South China Sea, often in company with the Nanyang Fleet. This cruise typically involved visits to Zhejiang, Fujian, and Guangdong provinces, and sometimes went as far south as stops in Southeast Asia. The rest of the year was spent in northern waters off Zhili, Shandong, and Fengtian provinces, conducting training exercises. Training cruises to foreign ports were conducted in the mid-1880s and early 1890s, both to train navigational skills on voyages far from shore and to show the flag. Discipline aboard the ships of the Beiyang Fleet was poor, which contributed to a low state of readiness of the ships. During this period, the fleet was commanded by Admiral Ding Ruchang, who employed Dingyuan as his flagship. At the time, China lacked dry docks large enough to handle Zhenyuan and Dingyuan, forcing the navy to rely on shipyards in Japan or in British Hong Kong for periodic maintenance. The two Dingyuan-class ships began their training routine in April 1886 in joint maneuvers with the units of the Nanyang Fleet, which culminated in a naval review in Port Arthur. They received the British vessels of the China Station from 19 to 20 May. Dingyuan, Zhenyuan, and four cruisers made the first of their overseas cruises in August 1886, which included stops in British Hong Kong, Busan and Wonsan in Korea, Vladivostok, Russia, and Nagasaki, Japan. While at the latter port in August, Chinese crewmen became involved in an altercation with Japanese locals that resulted in the deaths of eight Chinese sailors and two Japanese police, with forty-two Chinese and twenty-nine Japanese injured. The so-called Nagasaki Incident was characterized by the Japanese press as an attempt by China to intimidate Japan, leading to calls for naval expansion to counter the Beiyang Fleet. The Japanese government ordered three protected cruisers in response. The Japanese also refused to allow the Chinese ironclads to return for repairs in their shipyards, hampering the ability of the Beiyang Fleet to keep the vessels operational. The year 1887 passed less eventfully, with the ships spending the bulk of the year in the Bohai Sea.
