This article is a lyric prose, which describes people with things. My father, who works in Xinjiang, introduced the poplars growing on the Gobi Desert to his children during his trip and expressed his ambition to take root in the frontier. At the same time, he hopes that his children can take root, sprout and grow where they need it, just like poplars. The article praises the great ambition and dedication of frontier builders to obey the needs of the motherland and take root in the frontier.
