Who was the official known as Yu Qian's concubine in Ming Dynasty?

Yu Qian was a famous patriotic general in Ming Dynasty, and once served as the minister of the Ministry of War. Wang Zhen was a eunuch who lived in the same dynasty as Yu Qian. According to Qiao Dunlu, Yu Qian's assistant minister of the Ministry of War is Xiang. In order to please his boss, he followed Yu Qian day and night and often whispered in his ear. Sometimes people called him "Yu Qian's concubine". At that time, there was an assistant minister named Wang Hu, who was Wang Zhen's confidant, so beauty was unnecessary. Wang Zhenben is a eunuch. Of course, he has no beard. One day, Wang Zhen asked Wang Hu, "Why doesn't Assistant Wang need it?" Wang Hu replied, "My master doesn't need it. How dare my son? " So he was ridiculed as "Wang Zhener". Those who have good deeds will combine the two into one: Yu Qian's concubine; Wang Zhener's couplet should be regarded as a couplet. This is a collection of nicknames of Xiang and Wang Hu. Although there is no comment, it vividly depicts Xiang and Wang, two flattering and individualistic images.
