If you want to hear or speak Mandarin in New Jersey, the best thing to do is get a massage. Such differences are fundamentally different in Monmouth County than it is in a city like Changzhou.
First, there are all the prostitution stereotypes to contend with. Massage places and spas in China can sometimes be a front for such ellicit business ventures. The more legit places tend to be cloaked Chinese traditional medicine. Typically, these places are either storefronts or whole building billed as “spa hotels.”
In New Jersey, it is not the same. Chinese styled accupressure places are typically located in shopping malls. Many of the customers go to the mall to buy one thing, and then getting work done on their back or neck results as an impusle buy. As in, “Ooh! I want a massage, too!” The places usually tend to be very spare, and the only bit of decor might be reflexology charts. The other notable difference tends to the equipment. In Jersey, massage places tend to use specialized chairs that allow the massuese to focus on a person’s back, neck, and shoulders. There are also tables. Typically, most massage places in Changzhou tend to only use the table. Neither me nor my friends have more than a very few massage chairs — just the tables.
Interestingly enough, I have only seen Chinese immigrants and green card holders working at these places. You never see a non-Chinese person. Only on one occasion did I get a massage from a second generation Chinese-American who could speak English fluently. In most cases, many of these workers can barely speak broken English beyond, “How many minutes” and knowing body parts. Conversation between parlor workers always tends to be in Mandarin.
It would be a mistake to think these types of Chinese-centric businesses are common across the USA. I have seen mall massage joints in West Virginia that employed no Chinese people at all. In many regards, this is just one, of many, examples of how multicultural New Jersey can be.
