It's very simple.
As Jun Yang is the first daughter of the Imperial Family, when she was born, the Empress Dowager, in high spirits, promised her a substantial dowry in front of all the ministers, to be given to her upon marriage.

The dowry, for now, will be managed by Jun Ning, who will also supervise Jun Yang's behavior.
The Empress Dowager explained her ideas to Jun Ning, and fearing Jun Ning might not understand, she succinctly reiterated several times.
