Found on eBay: The Book of Erotic Change. The box says:
This is a very tastefully done 80 min documentary featuring over 60
different sexual positions and techniques as demonstrated by an
attractive young couple. Very informative, as well as easy on the eyes.
'Easy on the eyes'? In other words, boring? The Chinese description, "以易經啟發陰陽調和,男女魚水之歡的要訣,六十四式秘
技,為你增加無窮的閨房樂趣...." makes clear that every hexagram of the Yijing is linked to a position, 'to harmonize yin and yang'. Hm, they beat me to that, I had that in mind.
I like the expression "魚水之歡", 'the happiness of fish and water (because they are together)', which stands for the joy of being with one's true love.
Sixtyfour positions. I wonder: If you practice this, do you ever have time for other things?
Hexagram 10: 'stepping on the tiger's tail'. "Sorry dear. Does it hurt? Need some ice?"
