There is a couple in Sudden Weekly. After you have done the Yung-ying test, you may get a rose water (value at $80) for free. I did the test, did not buy anything and received a bottle of rose water (30 ml). The service is o.k. but I doubt the validity of the test. Seems so simple.
I went to the shop last month, but I do not have the coupon from Sudden Weekly, so I didn't get any free rose water from them.
Although I don't have coupon, they still did the yingyang test for me. For me, the result is amazing, may I have more problem with my body, eg. stomach pain, menstration pain, can't go to washroom for a few days, nose allergy...and I didn't tell them anything about these. It's so surprised that the girl can figure out all of them.
The service is quite good, the lady is quite professional and when I have lots of questions, she answers me patiently. I guess the girl that serve me is quite well trained or belong to more 'superior' level inside the shop because she didn't wear the same clothes (uniform) as the other sales girls.
Finally, I bought some products that they recommend to help my stomach problem. The girl even help me to mix the oil and teach me how to do simple massage technique...etc. I use it for one month, and problem has improved a bit.
The shop has some beauty rooms at the back for facial and body massage. The lady invites me to have a short 'look' or 'tour' overthere. At the end, she didn't force or hardsell me about their service at all. Just ask me to call them for details if I am interested later.
