Hi. I'm staying in Shanghai for 6 days next week with the 144visa on arrival.

I don't know where to stay yet in Shanghai. Thinking about couchsurfing. I found quite a bit expensive hotels so far. My question is: how can i register myself to the police? If it's a hard job to do? Losing a whole day? If so, i though about going my first night in a hotel (so they do it for me) and then leaving to somewhere else. Would this be ok?

Thanks
