There are profound sentences in the text "Poplar". I want to write one about my own experience.

Dad's smile disappeared and his face became serious. He thought for a moment and said to his son and daughter, "Poplar has always been so straight. Where it is needed, it will quickly take root and sprout, and grow thick branches. No matter whether it encounters drought or flood, it is always so straight, so strong, not weak and unshakable. "

From this sentence, we can understand that dad, as a frontier builder, encourages himself to be a real frontier guard and contribute to the frontier, and also hopes that the children will become excellent frontier builders and "poplars" who contribute to the motherland like him.
