Chinese gunboat Chung Shan

Chung Shan (中山艦；Zhongshan in pinyin), originally named Yung Feng (永豐艦; Yongfeng in pinyin), is a Chinese gunboat built in Japan in 1913 of 830 tons and later renamed in 1925 Chung Shan in honor of Dr. Sun Yat-sen, the founder of the Republic of China.

Construction
The ship was ordered by the Qing Government in 1910 and was built by Mitsubishi.

Service
In 1922 the Chung Shan fought its way past the Pearl River forts controlled by Chen Jiongming while carrying Sun Yat-sen and Chiang Kai Shek. On April 13, 1925, the ship was renamed to its current name in honor of Sun Yat-sen. The ship was also involved in the Zhongshan Warship Incident in 1926.

She patrolled the coast of South China against pirates after Northern Expedition.

In the Second Sino-Japanese War (1937–1945), she participated in the battle of Wuhan. She was bombed and sunk in the Yangtze River by Japanese invaders on 24 October 1938 with 25 casualties.

Aftermath
The shipwreck was salvaged from the river in January 1997. The salvaged and restored Zhong Shan gunboat is now located in its own museum in Wuhan. The museum is located in Jinkou Subdistrict of Wuhan's suburban Jiangxia District, some 25 km southwest of downtown Wuchang.
