All the Chinese dramas I watch praise the women having large eyes, almost all very round. They also emphasize the quality of the skin and the smallness of the face. My VERY favorite actor put out a book on male skin care.
This might just be current style. Some of the older Chinese paintings show the narrowed, slant style.

During the Qing Dynasty, very small eyes were considered most attractive. Today, all of the Chinese girls are going for double eyelid surgery and the biggest eyes possible - so their complaints in this case are not off the mark. The model looks like a Suzy Wong type from the 70's.
