What to do??

Hey all so iv been tryna get a job for a yr now but just get rejected or don't hear back. But now iv recieved an email from a company called pioneer and beyond about an english teacher job in China which is for a yr.
I did get offered a job doing this a few yrs ago with a different company callied haida but I didn't do it in the end. But now m considering it cos iv got nothing else going for me right now.
So has anyone here worked for them or done this before and can tell me what it's like??
