Lao as in ren+lao. I guess I can't post characters in these comments :((((
I lived in China for most of my adult life, and return frequently. I have a Chinese wife and an mother-in-law living in the house. I was moved there by my company (first job out of college), and now practically every aspect of my life is tied to that country. I can read baihua, as well as wenyanwen and do so frequently in my spare time. I am a Sinophile, in general, but I'm not going to pretend things are perfect there. A lot about life in mainland China scares the living heck out of me.
What I was referring to was extra-linguistic: to various hate-mongering websites that promote the wholesale ethnic cleansing of western China (usually "to prevent anti-Chinese minorities from potentially harming China's economic shift the its western borders in order to reduce dependence on American trade" and goes into tin-foil hat land from there), and, to a lesser extent, tracking and harassing foreigners in cities with small foreign populations. The usage of that suffix in my post was incidental.
