However, when it comes to marriage, Princess Channing has become a tool for the exchange of political interests. At that time, he was betrothed to Wu Sangui's son Wu, because Wu Sangui was an important official in the imperial court and made great contributions to the emperor's suppression of rebellion.
But the ancient emperors were so afraid of their officials' achievements that they even did something to betray them. Similarly, Kangxi was also afraid of Wu Sangui's rebellion, so it was certainly favorable to take Wu Sangui's son Wu hostage. Later, he married Wu to win over Wu Sangui.
But what should have happened still happened. The Wu Sangui Rebellion directly affected Princess Channing's life. Overnight, Princess Channing lost all her family, her dearest husband and children, and was arrested and executed by Kangxi. After that, Kangxi also tried to appease Princess Channing, but I can imagine how painful it was for Princess Channing. Later, Princess Channing never got married again. She lived alone in her 60 s and was widowed for her late husband for more than 30 years. This shows that they have deep feelings.
Regardless of her status, in fact, when she married Wu, she had already formed a family, not to mention having several children later. But even if Wu didn't have the heart of rebellion, he still died in the struggle for imperial power, leaving him alone for the rest of his life.
