Let us look a bit of the wording that indicate such a mail to be a scam:

Dear Teacher,
How are you doing today?hope that you are doing good.
I have attached the CONTRACT AGREEMENT LETTER,go ahead and read it then sign.You
will be sending me a copy and also a copy to the immigration
Lawyer,then you are going to keep a copy as well.My immigrations
Lawyers e mail is on the contract,go ahead and contact him,i already
informed him about you.

Genuine employers hiring foreign staff or faculty are most unlikely to hire a lawyer. Too expensive, and they would only need to do so if there was an issue that makes employment of foreigners illegal. The latter is either illegal or not. Which employer would take the trouble to fight a case in court before employing a foreigner? That's just rubbish!

He will be in charge of all your necessary
documentation including your working permit and the rest of your
paperwork.Go ahead and email him and he will get everything started
with you.

Sounds as if the prospective employee was promised paradise instead of work. A highly contradictory statement, and absolutely unprofessional for a real employer to say such a thing!

This pretend lawyer will then charge you for his "services", and the pretend "lawyer" himself is the same person that had sent this scam mail.

Once again we are looking forward seeing you here and you
should be rest assured once again that your comfort will never be a
problem and do send me a number to give you a call OK.

Sounds like talking to a customer, which employer would write such a thing to a future employee abroad?

Make sure you
have a wonderful day ahead of you and remain bless

Chinese employers would never wish anyone "remain bless"; as a rule, they are non-religious people.

Catch these scammers by their wording!
