First of all, it is very painful to marry someone she doesn't love at the right time, and obviously she has found someone she likes, someone she wants to spend her life with. But because of this marriage, the two separated, and her inner pain and pain can't be told to Shengchen Zhou, because he knows that Shengchen Zhou also has a lot of helplessness. Maybe if Shengchen Zhou refuses this marriage at the right time, Shengchen Zhou will agree, but it is also obvious that the time is ripe. If Shengchen Zhou refuses this marriage because she challenges the imperial power, he will also be criticized a lot, because he has refused to accept her as an adopted daughter according to the wishes of the Queen Mother and can't do more for her. So it's time to make it clear that I don't want Shengchen Zhou to see her marry someone else.
Secondly, after watching the whole drama, we know that Shengchen Zhou is responsive to everything and does whatever he says at the right time, so he was asked not to watch her wedding, so he promised her not to watch her wedding. In his mind, they are all in Zhongzhou City. Since she is in one place, sending her to a suitable wedding is the same as sending her to Zhongzhou to get married. If Shengchen Zhou leaves, it will only be sad.
