Dear Johnson,
     I' m glad to learn about that you and your family are coming to 
settle down in China. After a careful study of the informations about
the two citie, I suggest you choose to live in City A. First of all,  
City A is a more popular city to live. The environment in City A     
is better than in City B and the climate there is very pleasant.        
Besides, there are many places for entertainment which you can      
enjoy yourselves in your spare time. As for employ, though         
the job opportunities are not so well in City A, yet I don't think       
it was a real problem for you as a teacher of English.                
That is only my suggestion but it's up to you to decide.          
Hope to hear from you soon.
