Shenzhen smugglers

Hello guys and girls,
I always wanted to know about grey market smuggling industry. Have you guys ever had experience using China smugglers to bring something to hong kong? I actually wanna test it out. (I don't mean, I want to start smuggling)
And also before you guys bombard me with comments and replies like " you are promoting Hong Kong smuggling industry"
I hope i don't make any misunderstanding, I don't go against or for this industry. After all, no matter the regulation things like this always happen.
Also I heard these smuggler work in a very structural manner, where there agencies hiring smuggler that looks less suspicious and kind looking.
Overall, if you guys go to lo wu quite frequently, hope you guys don't mind sharing one of their contact to me. Furthermore, if i can, i want to interview them and hopefully gather some information to write an essay about the life style of smuggling,
(P.S just private message me, if you priorities on privacies.)

I'm not a police man XD

i am sure you are Police.. or maybe secret police...

That is some mind game to pull off dont you think?
