(Photo unrelated to my sighting)
I'm positive it's the famous SHD in HK. I myself had an amazing sight a few months back.
The first time I saw her pics was when I was still living in the UK. For unexpected reasons I ended up working and living near HK in Shenzhen. On one of my frequent visits to HK to see my old friends we went to IFC, a famous shopping centre. I remember we were looking for a couple of guys we had lost on the way when all of a sudden I saw her gliding sensually in front of me. I think, had I not looked ahead of me right then we might have actually collided with each other, for by the time I saw her she was almost a meter away from me! So I stopped and let her pass. She was wearing a greenish dress, very short, revealing her nice remaining leg. It was a brief encounter, no time for pics or anything, and plus I was with friends so it was awkward to follow, but I did have enough time to notice the graceful limp motion when her single leg took a step forward and upon contact with the floor the leg muscles took a tiny shock. I found that very sexy.
