Twice this year I've used the kind of approach recommended by Janka - highly personalized one - to open up conversation with a woman and both times I got a good reaction.

The first time was in an electronic music event. I saw a girl with 3 Chinese characters tattooed to his arm, and recognized that the middle one was 佛, which means Buddha. So I told her that I can recognize one of the characters and asked what the other ones meant.

The second time was in gym. A woman older than me had 2 Chinese characters tattooed to his arm, and I recognized that the last one was 火， which means fire. I didn't open that time, but memorized the first character and later tried to search it from dictionary without success. The next time I saw him I started with line "I see you have a fiery tattoo". She told me that the tattoo is a Chinese horoscope, fire horse.

Both conversations lasted for solid 10 lines, and were very much limited by my own approach anxiety. I saw the fire horse woman third time, greeted her and she greeted back, so there is reason to believe that it was a positive experience also for her.

Few girls have Chinese character tattoos, so I didn't consider these relevant from the seduction point of view. Thanks to Janka for pointing out a way to generalize these success stories.
