Force. On October 24, 1986, PLAAF pilot Zheng Caitian flew his Shenyang J-6 from Yantai to Seoul Air Base and when he reached Taiwan, he was awarded 5,000 taels (approximately 250 kg) of gold. Among the Chinese defecting pilots, Zheng has had the harshest life of all, because he invested in an electronic factory that went bankrupt, and lost all of his money in his subsequent investments. On November 19, 1987, Liu Zhiyuan, a squadron commander of PLAAF 49th division flew his Shenyang J-6 numbered 40208 from Longxi airport, Zhangzhou to Ching Chuan Kang Air Base in Taichung, Taiwan and was awarded 5,000 taels (approximately 250 kg) of gold. Liu invested heavily in the Taiwanese stock market and his assets (not including the gold rewarded to him) were once more than 10 million New Taiwan dollars (approximately 400,000 United States dollars). On September 6, 1989, Jiang Wenhao, a 23-year-old PLAAF lieutenant of the 2nd wing of the 145th regiment of the 49th division flew a Shenyang J-6 numbered 40307 from Longxi airport, Zhangzhou, Fujian to Kinmen Shang Yi Airport. Jiang was interviewed by the then chief-of-general-staff of Taiwanese armed forces, Hau Pei-tsun and awarded a rank of lieutenant in the Republic of China Air Force. Jiang's financial reward, however, was reduced to 2,000 taels (approximately 100 kg) of gold from the original 5,000 taels (approximately 250 kg), because due to the reduction of tensions with China during the 1980s, Taiwan had greatly reduced the amount on September 15, 1988, in response to similar Chinese action four days earlier. (China had completely abolished any financial rewards to any Taiwanese defectors). Jiang was soon honorably discharged from the Republic of China Air Force after being promoted to captain. Jiang became a famed underwater photographer and won several awards, and he also worked as a diving instructor. On August 25, 1990, Wang Baoyu, a squadron commander of the 62 Air Regiment of the 21st PLAAF Air Division, defected to former USSR by flying his Shenyang J-6 to Vladivostok after taking off from Jiaohe military airport in Mudanjiang (not to be confused by the city of Jiaohe and the civilian Mudanjiang Airport at Mudangjiang). A week later, he was turned over to China along with the aircraft (according to the Soviet eyewitness of the extradition procedure, Wang was severely beaten by Chinese escort detail officers as soon as they got him from the Soviets,)
