我当然是做过调查才和你说的呀！这个有固定套路的。就是利用香港作为自由港的便利，把鸡翅运到香港，然后再分批从广东各个口岸运进内地。

I looked into this before talking to you, of course! There's an established way to do this. You can use Hong Kong's status as a free harbor. You ship the chicken wings to Hong Kong, and then separate them into batches and import them to different ports in Guangdong.
