Dear editor,

I am writing to you to talk about taking up occupations for college graduates. Nowadays many graduates are looking forward to obtaining employment in big cities, not willing to work in the countryside.

As a matter of fact, there are not enough opportunities to satisfy most of the hunters in bit cities while in the countryside talented people are badly needed and a lot of posts are waiting for us. Rural areas are a vast world, you can put your abilities to good use and you’ll be able to make greater contributions to the building of new countryside.

Therefore, I believe we can have as bright a future in the country as we have in the city.

Yours,
