The highest-rated "cai er" ear cleaning service on Dianping, Weiwei sort of reintroduced the artform to the average Shanghainese schmoe back in 2015, when a young lady named Zhuju opened a nationwide chain. This one is in Tianzifang, located on the second-floor of a shikumen. The service, which involves an array of tools and an almost ritualistic approach to getting the gunk out of your ears, blends into the more private foot massage and spa world. It is mostly performed by ladies. They have a sister brand named Kuanzhai that's a little bit better.
