First of all, the texture of the picture on the left is not like a photo, but more like a composite picture. Cixi took some black and white photos in her later years, but there were no color photos in China when she was young. The recorded color photos in China are at least 1900 years later, and Cixi died in 1908. So the picture on the left is definitely not Cixi, nor can it be ancient China. It is meaningless to compare the two images.
However, Na Ying is Manchu, and it is said that it belongs to Ye Henala. She may be a distant relative, but she is not a descendant of Cixi. Emperor Tongzhi, born in Cixi, had no children.
