Teacher Sun is the math teacher in our class. She is of medium height and looks like 35 years old. An amiable face, always so kind. The eyes seen from those black-rimmed glasses are always so bright and kind. Her language is always so profound, so wonderful and makes people laugh.

The female teacher's surname is Song. Because she is young, she is only 20 years old at most. So we all call her Miss Song, and some female students kindly call her Big Sister. Teacher Xiao Song is tall and dressed simply. There are two arch eyebrows on the face of melon seeds, a pair of bright and sharp eyes embedded under the arch eyebrows, and a glib mouth. Teacher Xiao Song tied two long ponytails and dragged them to his shoulders.
