MassageRepublic

MassageRepublic is one of the larger international escort directories. It runs a busy Shanghai section and also lists Beijing, Shenzhen and Guangzhou and many other (non)Chinese cities.

Anyone can buy a listing there and the site itself verifies nothing, so read every profile as a claim rather than a fact. Recycled and heavily edited photos are common, and the same set of pictures regularly turns up under a different name, or in more than one city at the same time.
