Why did Queen Xuan commit suicide? Did Empress Xuan really commit suicide?

Since Queen Xuan was widowed in her prime, and now she is in charge of state affairs, she will certainly not be alone. Although as the queen mother, she can't get married formally, so she has many lovers. In fact, the first lover of Empress Xuan (recorded in history books) has a good relationship with her, which is a great event that benefits the country and the people. This man is Rong Di, the king of the Huns, a foreign territory of the State of Qin. When King Huiwen was alive, Yiqu joined and obeyed the State of Qin, while Qin Zhao succeeded to the throne, young and ignorant. King Yiqu, who came to Chaohe River, was strong and unruly, and looked down upon the new King of Qin. Every minute, he may resist again. Under such circumstances, Queen Xuan secretly approached King Yiqu as the empress dowager of a country, making him her lover. Naturally, his anger was greatly reduced and his rebellious thoughts were less. The location of Rongdi, outside the Great Wall of Qin State, is an important rear area of Qin State. It was because of the sacrifice of Queen Xuan's own color that Wang Changda of Itraconazole was saved for 30 years, so that Qin had no worries, freed up his hands to strengthen his national strength, and fought endlessly among the vassal States, and made repeated gains. Thirty years later, Qin has become the eldest of the vassal States, and its national strength is strong, so it is no longer necessary to fear the threat of Rong Di. So Empress Xuan chose an auspicious day to lure her lover to Ganquan Palace for a "holiday", and then suddenly attacked in Gentle Township, killing King Yiqu, and immediately sent troops to destroy Rongdi, taking away all the territory that originally belonged to King Yiqu in Ningxia, Gansu. From then on, the state of Qin was no longer worried about the western border, which laid an important foundation for Xuan Di's great-grandson to seize power and become Qin Shihuang. According to Sima Qian's Taishigong, the Queen Xuan gave birth to two sons for Yiqu King during her thirty years of contact with Yiqu King. But what happened to these two sons, I won't look at it below. If it was killed by the State of Qin headed by Empress Xuan, it must meet with historical records to further prove that "Qin Naihu Wolf Country". But there is no record that these two children may have died as early as 30 years before their parents met. In view of the medical and living conditions at that time, this possibility is even greater-and the death of his son is, of course, one of the factors that further prompted Empress Xuan to kill her lover. Why is it that the premature death of the sons of Queen Xuan and King Yiqu (if any) prompted Queen Xuan to finally attack King Yiqu? I just think that if Empress Xuan doesn't want to have children, she can have them without pregnancy, and she really did. Her original intention was to use the empress of Qin and the son of Yiqu Wang to inherit the throne of Rong Di, thus avoiding the hidden dangers of Qin State and returning Rong Di to Qin State without bloodshed. However, both sons failed to develop and could not have any more children. The soft blood policy failed, and she finally killed King Yiqu. Just guessing, please don't argue. In a word, Empress Xuan made full use of all her advantages as a woman, played to the extreme, and even reached the goal that many troops could not reach. Unfortunately, for King Yiqu, equating this delicate woman with the weak can only lead to such a fate. Seek adoption
