Its very wrong and unfair on students if you ask foreign teachers to stay away from this city.Its also an irresponsible and wicked assumption that i work and recruit for a Miss Liu.There are so many foreign language schols in the city.If you have had a bitter experience with your own employer for whatever reason you should be sure who you are dealing with not blackmailing unreasonably .If you deny students in this part of china what their counterparts in other areas benefit in foreign teaching as a result of your bitterness and outburst ;PROSTERITY IS THERE TO JUDGE YOU.
