Honestly, I don't think we care what it means, the fact that it has Chinese lettering and that head doesn't typically put Chinese lettering on any of their racquets let alone pro stocks.
Also, your "hairline crack" - a lot of paintjobs have hairline paint fractures at the 6 o'clock face if you look down ontop of the grommets. I had a pt57e that was brand new and never hit with, and it develops it because they use a very thin coat of paint to not affect the specs. If that is your hairline crack it is just the paint and not the actual frame.
