What are the three types of "imperial photos" taken by Yu Xunling for Cixi?

During his tenure as a court photographer, Yu Xunling took many "royal photos" for Cixi. These photos are divided into three types: one is a full-length photo of a single person, some are wearing royal clothes, and some are wearing casual clothes. The second is a photo of Gong Wei's life. Third, make-up entertainment photos, some taken indoors, some taken by boat on the water, with different characters and different scenes. Most of Cixi's makeup photos are dressed as Guanyin, and the brand of "Master Guanyin of Putuo Mountain" is nailed on the set or screen.
