Yeah, good idea!
Basically, my understanding thru this process is that you want to avoid Shanghai Customs at all costs so we went thru Guangzhou. I hired an "agent" at 5000rmb to squish the GZ quarantine. Yes I know that sounds pricey, but the US and HK agents want anywhere from US$4000-6000; the high end one would have gone through Shanghai. None of the others would touch Shanghai. So I figured there must be SOMEONE in China doing this and I found one. I hesitate to publish his website, because... well, read on.
So what did this "agent" who apparently has an "office" at the airport in GZ do? Well.... I'm not sure. All I know is that the airport and airline staff waved me right thru. The guy was supposed to meet me at customs with paperwork looked "really offiical" - hand written, really bad English translation - that he had scanned to me when I was ready to board the plane at LAX. I emailed back that I would do it when I arrived. This "paperwork" is certainly not the work of the Chinese Govt. But when I arrived there was no paperwork, no agent, no one at customs ready to check the dog. This was a very different experience when I originally came from Guadalajara with the dog to Colorado Springs. Chest thumping Napoleonic TSA agents all over the place, but in GZ, no one was there and I was waved and pushed right through.
I didn't see the "agent's agent" until I was ready to book my seat (and the dog's) on my connecting flight to Hefei. I'd figured I would see or hear from him eventually. He wanted his money. The "agent" purchased the connecting flight for me which has caused problems for me getting reimbursed from this university I am working at. And he didn't purchase the part for the dog. So at the very least purchase your own tickets.
Now I'm wondering if customs just dropped the ball and this guy just stole money from me. Or did he really make customs go away? I don't know. All I know is she's here, I'm here and there was no quarantine. And we are living happily ever after.
