When it comes to the scene of spring, people often quote "in the spring of March, the grass grows in the south of the Yangtze River, the peanut trees are mixed, and the warblers fly around". When it comes to the scene of autumn, it is often expressed as "golden autumn in October, crisp autumn, clear sky and fragrant osmanthus".

On the Mid-Autumn Moon Night, sweet-scented osmanthus is fragrant and fragrant. Every year on the 15th day of the eighth lunar month, people burn incense and light candles for the gods of Yue Bai. Children often play with laurels to show that "the moon has won the laurels" and won the highest prize. When it comes to sweet-scented osmanthus, people often feel successful and rewarding. Such as "Gui", such as "Bukan Palace, folding Dangui".

Teacher's Day is just in September, and osmanthus flowers are in full bloom and fragrant. There are few other flowers except chrysanthemums. Autumn is the harvest season again. Therefore, sweet-scented osmanthus is often used to symbolize the great gains made by teachers' obscure efforts. In the past, "peach and plum fragrance" was often used to express this meaning, but at this time, some sense of season was lacking, and Dangui was at the right time, so Dangui was associated with education. And it's getting closer!

That's what I thought. It's completely connected. There is no reliable allusions to support it.
