anyways.. let's not talk about you should use "unlaw" or illegal ... shouldn't  be it's a Law in China that sex related trades is illegal.. and it's "unlawed" .. or whatever in Thailand ...  However, i don't think just make sex trades legal can make more people visit China, it will cause contrition to Chinese culture. For example, will you let yours wife you sex with yours friends in order to get more friends? it's just not the way a person or country will act..
p.s shouldn't the title "who known this question" be "Who Know The Answer Of This Question?" .. and i am really think u r underage for this website from yours undeveloped and the understanding for society.

Sorry about the double reply here.. but it's really funny how list.cao replied..
"Hey guy, your English is very good, this is the first time I heard "law" and "unlaw""
First, "hey guy" ... guy is third person... saying "hey guy" it's like saying "Hey he" .. maybe you thought "hey guy" is fine since "hey guys" is fine. but "guys" act like " you" and "guy" is just "he/she"
second, u can't describe "english" with "good" ... common sense i guess..
thrid, first time i "hear the words" law and unlaw.

do you think china have to use this kind of idea to attract more visitors or to grown their economic?
or you just hunger for sex only?
or... you been caught by police during you having sex trading with...?

I don't think making sex trade legal is a good idea.....
If it is legal, it may bring economic advantages but more important problems like spread of AIDS, effects towards woman and reputation of China should also be considered,

sex is mony out china ,but in china ,sex is muder!

OMD, what are you guys talking about... This is an erotic website!
