Job Interview Via Phone

I took a job interview last evening.
The job was teaching the Japanese language in China.
A teacher at the college made a phone call to me and we talked in Japanese.
I had thought the person in charge would be a man but it was a woman.
She explained about many things such as the environment of the city and the job itself.
As a result, I declined my offer, because the city is heavily polluted by smog during winter.
The benefits of the job is good but I cannot live in polluted air.
I will look for another job for the next school year.
