People often use poems and words to describe teachers' love for students, and the more explanations, the better.

Silkworms in spring will weave until they die, and candles will drain the wick every night. Teachers are very hard-working and dedicated.

Sneak into the night with the wind, moisten things quietly, teachers cultivate students in obscurity, and influence students imperceptibly.

Guide education step by step, and teach carefully and patiently.
