As we all know, the Langya Zhuge clan in the Three Kingdoms period at the end of the Han Dynasty had members of the Ji Han, Eastern Wu, and Cao Wei. In addition to the most well-known Ji Han Chancellor Zhuge Wu Marquis, Zhuge Wu Marquis's brother Zhuge Jin achieved the high position of a great general in Eastern Wu, and he was also an extremely popular subject.
However, compared with his younger brother Zhuge Wuhou, who ranked among the Ten Zhe of the Wumiao Temple, Zhuge Jin's military talent was much lower, and he had hardly fought a few victories in this life, and the victory rate was comparable to that of Xiahou Huan of Cao Wei. So why did Zhuge Jin, who had hardly won a battle, still become a great general of Eastern Wu?
The Eastern Wu regime as a whole consisted of three major groups: the native warriors of Jiangdong, the native warriors of Jiangbei and the southern migrators, and the military heroes. These three major groups can be divided into three major factions: the three dynasties, the two dynasties, and the old Wu lord, and the relationship between the various political groups in Eastern Wu is very complicated in the three kingdoms.
Sun Quan himself most trusted the old faction of Wu Lord in the two major groups of Jiangbei and Southern Qianshi and Military Meritorious Scholars, because they had shallow roots in Jiangdong and were closely related to Sun Quan. And Zhuge Jin, the brother of Zhuge Wuhou, is precisely the representative of the old faction of Wu Lord in the Southern Migration Clan of Jiangbei.
Zhuge Jin was born in Langya (琅琊, in present-day Linyi, Shandong Province) and fled to Jiangdong to escape the war. Zhuge Jin became acquainted with Sun Quan during his travels in Jiangdong and was one of the very few Eastern Wu ministers who had formed a monarchical relationship with Sun Quan during Sun Ce's time. Therefore, Sun Quan's trust in Zhuge Jin was extraordinary.
Due to the complex relationship between the political clique and the political faction in Eastern Wu, the Eastern Wu generals have always had the problem of insufficient coordination and loyalty. This is also one of the reasons why Sun Quan would rather be repeatedly beaten as "Sun Shiwan" by Cao Wei's famous generals but still repeatedly recruited himself, because he could not trust the generals of Eastern Wu.
However, due to the topography of Eastern Wu, Sun Quan could not personally take charge of the entire Eastern Wu defense line. Therefore, Sun Quan personally took charge of the war on the eastern front of Eastern Wu, and entrusted the war on the western front to the generals he trusted enough, and the four governors of Zhou Yu, Lu Su, Lü Meng, and Lu Xun were appointed for this reason.
However, compared with Zhou Yu, Lu Su, and Lü Meng, Lu Xun belonged to the native warrior clan of Jiangdong that Sun Quan did not trust. Coupled with the proximity of the Eastern Wu Western Front to The Ji Han Dynasty, Sun Quan appointed Zhuge Jin as the Left General, The Inspector of Public Security, the False Festival, the Marquis of Wanling, assisted Lu Xun, and balanced the native warrior clan that Sun Quan did not trust.
It was precisely because Sun Quan let Zhuge Jin lead the army to fight because he was wary of the Jiangdong Shi clan and not because Zhuge Jin had high military ability, so Sun Quan did not care that Zhuge Jin almost did not win the battle but let him balance Lu Xun. Therefore, Lu Xun and Zhuge Jin were also bound together in their careers, and they were promoted and glorified together.
In the first year of the Huanglong Dynasty (229), Sun Quan was officially proclaimed emperor, and Lu Xun was also appointed as a higher than the great general for his merits, "Shangda General (Sun Quan invented it specifically for Lu Xun)". Since Lu Xun had become a great general, Zhuge Jin, who had hardly won a battle, was also appointed as a great general.
