They are Xi Shi, Wang Zhaojun, Diao Chan, Yang Yuhuan.

I know one is Diao Chan for sure.

I really enjoyed these lovely pictures, thanks for sharing.

In order from top to bottom:

Diaochan

Wang Zhaojun

Yang Yuhuan

Xishi

Wang Zhaojun can be recognised from her pipa, Yang Yuhuan from the Tang fashion she wears, Xishi from her laundry-maid image, and Diaochan is just by elimination

Thanks for the exact identification, Yun. I was kind of wondering who was who....

Gweilo, you're welcome. :-)

Jieming

I thought that Diao Chan was made up for Three Kingdoms.

Hmm, I thought Yang Yuhuan was supposed to be slightly plump?... She looks pretty slim to me in that painting.

Also, I'm not very sure who Wang Zhaojun was (my history is that bad, argh). Was she the woman who went to live with and pacify the Xiongnu or something?

these women are beautiful if these are real, i'll meet xishi and Wang Zhaojun.

this pictures are very beautiful

These look like the work of artist Zhao Guojun or Wang Meifang. Can you enlighten us, Liang Jieming?
