Is your RP still valid?

I mean the dates... from... to

By my sums, you had a one yeat RP, so worked for 6 months, left your job then travelled.

It could be difficult to say you were still working when travelling because every hotel you stayed in checked you in on your RP. You have a paper trail.

Might be best to be honest.... just in case.

Even though your FEC is canceled, you are allow to stay on as a tourist (can't work) if your residence permit is still valid. ONLY if your residence permit has expired, you are leave before it does or be considered an illegal.

But while your residence permit is still valid and you have found a new employer, they can easily get you a new FEC online and you don't need to leave the country. It's the medical that you have to do if the last one done was over 6 months ago.

But both your FEC (canceled) and residence permit had expired, you need to get the hell out !! Should leave before your residence permit expired. Simple as that.

Technically yes, a Z visa expires 30 days after you enter China, and your RP then takes over and works as your visa. But since RP is issued based on "work", if you leave workplace you have 10 days to change employers, or leave China.

That said, reality may be different. It would depend on where you are located, and the mood of the officer dealing with you at PSB.
