Improper citation in part of the Kerria japonica article: Apology statement regarding "Speechless, Yet Longing"

On the evening of May 26, a netizen left a comment under the article "Speechless, Yet Longing," pointing out that: in the article "Speechless, Yet Longing," the description of mixing "yamabuki-iro" using traditional Chinese painting pigments, as well as the textual research in the annotations to "The Pillow Book" regarding how Kerria japonica petals echo the line "Speechless, yet longing," were both quoted from the article "Yang Yueying: Tangdi and Ditang," but the source was not indicated in the footnotes.
