Also, as any pretty girl in a DongGuan city's Sauna will teach you, put all portable objects inside the room's wardrobe and cover everything you can, including mirrors, with towels, bedsheets, or whatever piece of cloth you can find. Put all flasks of Shampoo or body soap in the wardrobe aswell. Scan the long curtains of the room's window with your eyes and hands. They are really professionals there.

Covering the mirrors, as the oldschool fingernail test is not sufficient to detect all kinds of two way mirrors

Sorry I didn't understand well your comment, if you are saying that the pretty girls cover the mirror to detect two way mirrors, that is not the reason they cover the mirror for.

I mean they cover the mirrors because detecting two way mirrors isnt as simple as putting your finger on it and looking for the reflection.

If you look at the picture

You see the difference between glas two way and standard mirror. That was recommended for a long time as a tip for girls to figure out if they have to worry about a cam being behind a mirror.

That however is not sufficient, which gets you from trying to detect a cam to taking precautions as if there are cams you just havent found yet.

Why do they cover the mirrors then ?

Same reason people draw the curtains - if it is a two-way mirror, then covering it prevents it from being a window.

Exactly, but the person I replied to said:

"if you are saying that the pretty girls cover the mirror to detect two way mirrors, that is not the reason they cover the mirror for."

Thus my question. If it's not to cover up a two way mirror, then what ?

Detecting something and protecting from something are different things, as Cf498 said in his comment, they just go directly to the protect step and ignore the detect step. They don't have time for Detect step. Its just that in the way he phrased his first comment, it was unclear, but I didn't assume that he was actually confusing the 2 steps, that's why I used "if" and said that I didn't understand clearly. Actually he didn't needed the info in that answer, but some others readers could get confused, as it seems to be my case. Now if you ask me how could I possibly think that cover a mirror is a way to detect a two way mirror, then I have to say I don't know, but maybe I imagined that if its day time, and the curtains don't provide enough darkness, you could cover the mirror with your head inside the cover to provide enough obscurity for your eyes to see trough the two way mirror. So maybe my imagination went too far, but yeah.

Why DongGuan? Wouldn't this be good advice anywhere around the world? Or is this some kind of in-joke I don't get?

First result on Google.

Your Google is not my Google apparently.

The filter bubble is real.

i guess it's play on English meaning of dong, while at same time Dongguan it's sex capital of China due to high ratio of women:men, this would of course apply same to Pattaya in Thailand or Clark in Philippines

Just to make a fun comment, in a humorous way, not criticizing your comment by any chance, just that I thought it was fun: Actually, They are sex capitals not due to high ratio of women:men, It's the opposite way: They have a high ratio of woman:men due to they being sex capitals. Donguan at it's Golden Age had probably 100 woman for each man, but if you go there today, unfortunately, it brings tears to one's eyes to see the sad state of less then 3 to 1 ratio. Or much less. In a certain winter, of heavy snow, someone was trapped for days in a train blocked by the snow, and this was time when workers go back to their hometowns for the chinese new year. This train was coming from DongGuan, and the ratio of women men inside that train was marvelous, not far from a Thousand girls to each man. This is all over now. Even the snow in China does't fall as much anymore...

except in Dongguan that ratio was not because of prostitution, but because of manufacturing unlike other sex destinations

So what explains that the ratio has absurdly dropped after the Police crackdown? Manufacturing is still going on here, actually, manufacturing there is growing stronger as ever, with the workforce Surplus, now, salaries of factory girl workers went down a lot, because we don't have other things to do now besides work in the factories now, so manufacturing has nothing to do with this, and even if it had, a city doesn't become a sex capital because of high-ratio women:men, would be overly simplistic reasoning, and that's what I was replying to,

If this was true, please mind, BaoAn district that belongs to Shenzhen (and where you cannot find a single male boy among thousands of pretty girls if you go to try to get a table at a cheap worker's restaurant at lunch time in a big factory's gate), and every other labor-intense manufacturing hub all over Asia would be Sex capitals, what is not true. The district of BaoAn, in the border between Dongguan and Shenzhen, actually geographically located much more close to Dongguan, but belongs to Shenzhen, and because it belongs to Shenzhen, and not to Dongguan, Sex business is "forbidden", or at least nowhere as freely allowed as Dongguan(was), you can't compare. What get us to the reason a city becomes a Sex Capital in a country where prostitution is forbidden by the law(!)

The reason is that the Gov of that country thinks prostitution is a necessary evil that helps to prevent violence and rape and other things, so this Gov indicates a place where this can happen, for the sake of Society's Harmony(SheHuiHeXie). Almost Every city in China has a street, a neighbourhood, or an area where the Police pretends to crack but let it happen, at least until people start to abuse the relative freedom, because humans cannot have nice things without abusing it, then they will indicate another place to start from scratch.

Vietnam too.

Even

:adding some historical context: It is said that when the Old Wise Man, and this was a Wise one, mind you, Lao Deng (Old deng Xiao Pin) Decide that the few thousand people small fisher's village named Shenzhen was meant to become the 10 million people's Heart of Pearl River's Delta(the biggest Industrial Manufacturing Hub Ever built by hummanity, probably) Lao Deng decided to aloow the creation of what was called back then ErNaiLou( in a literal translation word by word: Second Milk Building(not clear)), but this was a building full of small rooms for the factory workers to get SocietyHarmonized( In the good meaning of this verb, it has a bad meaning too, related to execution of death penalty)

> put all portable objects inside the room's wardrobe

I'm sorry, but how does this help?

Could contain a battery powered camera

Oh, the things in the room. I thought the comment was talking about putting your own portable devices in the wardrobe.

Yes, but they will ask you to put your own portables devices in the wardrobe too, including watches and glasses, even when the glasses have almost no frame to speak of. This is, or was, in the golden times, coincidentally, or not, the industrial hub with more relative freedom for production variety. The state-of-art of the spycamera-ware produced over there back then would make any old shop owner in Shenzhen's eletronic market simply jaw-dropped. Off course, if the guys in Shenzhen weren't afraid of jail, they would have the same stuff at some point. Is a pity people messed up doing too much GSM stuff. You can't have nice things. Same goes for the other industry mentioned. Just Nostalgy left. A lot of legal stuff could be mass-miniaturized by removal of case and tape cover. Long time retired now, don't know last progresses, but probably best stuff available for simple mortals still in Romenia. Best available for simple mortals in the other industry probably still in the same country. Never go near device starting with a J, may become guest of enhanced interview facility. The old memories...
