AVIC Property called and said that the recruitment was true?

Not necessarily. I'm just a recruiter. Companies will spend money on some talent websites to buy your resume. They can watch it even if they don't vote. But just now you said there is no AVIC property company in Shaoguan. I suggest you ask clearly first and explain your question "Why didn't you see Shaoguan's company online?" See what they say. If it is ambiguous, it may be a liar. If they can give a specific address, you can find it online, which may be true.
