Lin Wanyi had mentioned to the Emperor the idea of sending the Second Prince to the Empress Dowager to learn more.
With the Empress Dowager bringing it up, it saved the Emperor from having to speak.
He was, of course, glad.
"What Mother said is true, but a prince should be a little playful. How about letting him and the Third Prince come to Mother here after their studies to learn about the rules, but they return to their places to live. What do you think?"
"Hmm, the Emperor has thought it through thoroughly, let it be done that way."
They are all the Emperor's sons, and it's not good to favor one above the others.
If the Second Prince came and the Third Prince did not,
Princess Consort Yi would surely find a problem with it.
Rather than letting a trivial matter disturb the peace of the harem, it's better to keep things fair.
By sending them all, there would be nothing to say.
In this regard, the Emperor's consideration was indeed thorough.
