Analysis of information sources in references of the Wikipedia article "Yishiha" in Uzbek language version.
By 1420, Yishiha's experience, character, record, and judgement had certainly made him not only an expert on the frontier defense of the region, but also might well have provided him a coat of armor that protected him against jealous and wily court rivals. His next mission to the Nuerkan Command post ended in 1425 as he and his party were awarded by Yongle's successor, the Emperor Hongxi. During the reign of the fifth Ming sovereign, Emperor Xuande, Yishiha was dispatched at least three more times to the lower Amur River, inspecting, spreading imperial will and Ming policies, and reporting on the frontier defense and general conditions of the region. In 1432, when the commissioner in chief Kang Wang retired, Yishiha escorted Kang's son Kang Fu, who resided in Beijing at the time, to assume his inherited position. A part of 2,000 soldiers and an armada of fifty big ships arrived at the Siberian frontier fortress during the summer season. Almost immediately, Yishiha ordered the refurbishing of the Yunning Temple and the erection of yet another stone stele to commemorate the occasion. All told, Yishiha had made a total of nine missions to this desolate but strategically important region, pacifying the minority groups and serving as Ming's expansionist agent.18 Yishiha was later promoted to grand defender, or zhenshou, of Liaodong and received an annual salary of forty piculs of rice in 1444. Three years later, he was awarded an annual increment of thirty-six piculs of rice as a consequence of a memorable military campaign.19
