Asian Ear Cleaning
I found this link via Zod. It’s true in China too — Chinese people do pay a lot of attention to cleaning ears. In the USA common tools found on keyrings include bottle openers and penlights. In China the little metal “ear wax scoop” is quite a hit. It may seem dangerous to one’s hearing to use one of those things, but you see people using them around town (no, it’s not pretty), and I don’t think it’s causing widespread hearing problems.
The way this “culture of ear cleaning” affects me personally is that when I go to get my hair cut, that comes with a shampoo, and an upper body massage, and an ear cleaning, all for 25rmb (just over $3). They do use Q-tips. It’s a weird form of vulnerability, submitting to a stranger’s Q-tip.
