Received the recruitment reply from the Sixth Engineering Co., Ltd. of China Railway 18th Bureau Group, with their official seals on it. How can I tell the truth from the false?

It's fake. I got it, too? Do you think the same email will send recruitment information from two different engineering bureaus? Hey, yo, open their files. It looks quite formal. In fact, there are many typesetting and word funnels in it. Think about it yourself. If you don't believe me, you can go to other people's official website and check their contact email.
