Do you like animals? Do you want to work with them? If your answer is “yes”, you might be interested in the job of a vet.

A vet is an animal doctor. There are over 60, 000 vets in the US. Some take care of pets like dogs, cats and birds. Some care for farm animals like horses and cows. Some work in zoos and they work with elephants, tigers, lions, pandas and so on.

It's difficult to become a vet in the US. Besides the love for animals, one has to study really hard. He must first finish college, and then go to the veterinary(獸醫(yī)的)school for four years’ study. Working as a vet is not easy, either. They often work long hours, but many vets say that their job is exciting and fun.

This poem was written by a middle school student in a lonely mountainous town in Yunnan Province during her first poetry class. The girl missed her mother, who died when she was 5.

Kang Yu, the teacher who taught the girl how to write the poem, graduated from Renmin University of China in Beijing in 2015. Soon after her gradation, Kang moved to a town in Yunnan, and worked as a teacher at a middle school there.

As the classes grew in popularity, Kang became the school's favourite teacher. After she finished her teaching at the school in June 2017, she returned to Beijing and planned to study abroad.

However, on Teachers' Day in 2017, Kang received a big box full of poems and letters written by students at her old school. She felt she was needed and decided to abandon her plan of studying abroad. Instead, she set up Enlighten our Future, a charity that reaches students in the countryside how to write poems.

"Now, I go to several places every week. I sleep less than six hours a night and the job provides no vacations and little money, but the happiness and satisfaction I feel is rewarding enough." Kang said.
