Many old ladies (but very few young women, fortunately) in Qingdao and Qingdao only, are now wearing a nylon mask to protect their skin from the sun. Shopkeepers say it also protects your neck from this green algae which blankets Qingdao beaches every summer since 2008. A “Facekini”, as it’s now called (see bottom of the page) costs 20 rmb, so hurry up ! I bought the blue one. To purchase my pictures, or videos, on the subject: jordanpouille @ gmail.com
edit August 22: We shall thank the genius who created the word “Facekini”. It now brings so much attention to this delightful subject. I chose to add it on my link, to boost traffic.
