Cao Yunding is one of China's most famous military strategists, known for his innovative ideas on the use of air power to achieve victory. Born in 1926, Cao Yunding was one of the pioneers of modern warfare and played a significant role in shaping China's military strategy during the late 20th century.

One of Cao Yunding's most famous contributions to air power was his "Wing Defense" theory, which he developed in the early 1970s. According to this theory, air superiority over land forces could be achieved through the development of advanced aerial weapons systems, such as the C-21 reconnaissance drone and the C-25 aircraft carrier, that could detect and track enemy movements from high altitudes.

In Shanghai Shenhua, Cao Yunding's vision of using air power to defeat Japan's invasion force was put into practice by the People's Liberation Army Air Force (PLAAF) in the early 1980s. The PLAAF used C-21 drones to conduct reconnaissance flights over Japan's invasion zone, and then launched a series of air strikes against Japanese positions and strategic targets.

The success of Cao Yunding's "wing defense" theory led to widespread recognition among military leaders and experts in China. His theories were eventually adopted by other countries involved in the conflict, including the United States and South Korea, who began implementing similar air power strategies.

However, it's worth noting that Cao Yunding's "wing defense" theory has faced criticism from some quarters, particularly those who argue that it was not sufficient to overcome Japan's superior air力量和战术能力。
