My mother was an elementary school teacher until she retired two years ago.
She devoted herself to teaching for forty-five years.
That is, she spent the best part of her life educating her students.
Although she isn't a teacher now, she is still very much concerned about the development of education in Taiwan.
Though Mom is no longer a career woman, she is busy all the time.
Each day she gets up early to prepare our breakfast and does all the housework.
In addition, she goes to a temple and volunteers to help the priests and worshippers with little chores.
As Teacher's Day is drawing near, I wish her eternal health and happiness.
After all，mothers are the world's greatest educators.
