Here is my 2 cent about Rain... I do agree with both hongkong2012 and tybear that Rain can be difficult to work with (used her service a couple of times) and communicate with. She is very straight to the point which is probably is different than other mamasan and papasan most of us have encountered in the past. This is why for me, I would only contact her when i know what and when i want it
i have had a couple of bad conversation with her if i didn't reply or if i ended up not using her service thus this is also the reason why i stopped using her in Shanghai and look elsewhere.
For the girls, I have seen 5 girls from her shop now. Shanghai current status is making places like Rain milk the cow, there isn't much out there at this moment. By far the best service that i can say is Abbey and Jenny but always on her phone . The others are very heavily photoshop and definitely much older than posted age. Back in the Shanghai golden age both won't have stand out at all but at the current situation it is hard to get more.
I've encountered some wechat agencies that use to be saunas and now work as escort agencies but they require the people to be able to speak, read and write Chinese, have alipay/wechat to pay deposit and 0% tolerance on foreigners. However, not sure if I would want to transfer money for deposit since it will be trackable back to me... plus.... these agencies are damn expensive...
If only things would go back to what it was years ago.... HongKong2012 and Tybear hang in there! I do too feel your pain
