Wei Zhongxian was just a greedy eunuch who had read books and knew Braille, and did not have any level of governance, but he understood a truth: he was a nine-thousand-year-old who was promoted to the throne by Emperor Ming, the interests of the eunuch group were highly consistent with the interests of the imperial family, the Ming room was in his rise, the Ming room was dead, he died, he and the emperor were both cold and cold, and the leader of the eunuch group, Wei Zhongxian, would try his best to protect the Ming Emperor and the Ming Dynasty.
The political form of the late Ming Dynasty society was very chaotic and complex, and the contradictions between the central and local governments became more and more acute, mainly manifested in the fact that the local family clans annexed land very seriously, coupled with the fact that the local powerful factions had the privileges of the powerful and often evaded taxes, so it led to the financial constraints of the central government in the late Ming Dynasty, and when Emperor Mingxi succeeded to the throne, internal and external troubles intensified, and the emperor could not come up with money outside the internal and external security, but was often constrained by the civil official clique, and it was difficult for the government decrees to leave the city of Beijing, so it was deliberately cultivated to cultivate a clique of eunuchs to suppress the clique of civil officials.
It has to be said that the efficiency and means of the eunuch clique are much higher than those of the civilian official clique, and the eunuch clique is densely packed from the central to the local party, so it is very efficient to make the above government orders accessible, especially in the government that the emperor urgently needs, and also restores the industrial and commercial tax, touching the cake of the family clan, so it has repeatedly made up for the deficit in military expenditure on the battlefield of Liaodong, and indeed has the effect of renewing the life of the Ming Dynasty for a short time.
Later, during the reign of Chongzhen, the eunuch clique was dominant and directly threatened the imperial rule, so it was fatally dealt by the new monarch, and after Wei Zhongxian's death, the eunuch clique withdrew from the historical stage, and the civil official clique rose again, but the rise of the clique of civil officials did not do any good to the imperial court, but was a hotbed of corruption, and even less than the practical significance of the eunuch clique.
To sum up, it shows that the eunuch clique headed by Wei Zhongxian had certain merits in the late Ming Dynasty, but there was not much direct connection with whether nurhaci entered the border pass or not, and the border pass problem was mainly a military issue, and it was the credit of the border guard.
The first is because at that time, the Jin dynasty fought on two fronts, not only confronted the Ming army in Liaodong, Nurhaci also personally conquered the Mongolian Khalkha, into the Sila wooden wheel, and the active Mongols in the west were more threatening to the passively defending Ming army, so Nurhaci put the focus of the war on the west, and the Ming Liaodong battlefield was not the main direction of attack.
The second was that Yuan Chonghuan had outstanding military command skills and repeatedly defeated the attacks of the Later Jin army. Yuan Chonghuan took advantage of the advantage of the geographical advantage of the city to defend properly, and then deployed red-clad cannons, which caused heavy losses to the Jurchen cavalry, coupled with the proper tactics of sending troops, and won successive victories in Ningyuan and Ningjin, making it difficult for the Later Jin army to break through the border fortress.
