The spring silkworm spins its cocoon and spins out the silk only when it dies, and the wax candle like tears cannot drip dry until it burns out and turns to ashes. Praise the teachers for their selfless dedication and noble qualities of sacrificing their lives for the cause of education. ：

Untitled·It’s hard to say goodbye when we meet

Tang Dynasty? Li Shangyin

It’s hard to say goodbye when we meet It is also difficult, the east wind is powerless and the flowers are withered. The spring silkworm's silk will not be used up until it dies, and the wax torch will not dry until it turns to ashes.

When you look into the mirror at dawn, you are worried about the clouds on your temples. When you sing at night, you should feel the cold moonlight. There is not much way to get to Pengshan, and the blue bird is diligent in visiting.

2. Explanation

The opportunity to meet is really rare, and it is even more difficult to part ways. Moreover, the weather of late spring is about to end with the east wind, and the flowers have faded, which makes people even more sad. . A spring silkworm spins a cocoon and spins out all its silk only when it dies. A candle burns out and turns to ashes before the tear-like wax drips dry.

When a woman dresses up and looks in the mirror in the morning, she is only worried that her lush, cloud-like hair will change color and her youthful appearance will disappear. If a man moans and cannot sleep at night, he must feel the cold moon encroaching upon him. The other party's residence is not far away from Penglai Mountain, but there is no way to get there and it is out of reach. I hope there will be a messenger like a blue bird who will diligently visit my lover for me.
