They are different girls. When I went once with Lulu, she proposed a 2 girl massage with her friend Yan-Yan. That's not Yen (Yenchi, Yen-Ye) who is the very tall one I saw during the week.
Not easy with Chinese names.
There is (or has been) a girl called Yan-Yan (sometimes called something else, maybe Helen). Average size and look. Then there is the tall one, from Manchester (I thought her name was Yen-Ye, you said Yan-Yan, others have referred her as Yenchi, or Yin, or Yen)
