Why are immigrants obsessed with the big locust tree and the old stork nest?

It is difficult for a poor family to give up and leave their hometown. No matter how good the place is, I can't bear to live in my hometown for generations. People love their hometown and miss their relatives. It's heartbreaking where you will go. In front of us, the guards were tight, staring at each other, yelling at each other, drinking each other, holding knives and whips, beating about the bush and treating immigrants as criminals. Here, they lost their freedom, leaving only each other's thoughts, sadness and tears. When they cry, cry dumb, and get lost in thought, the big pagoda tree in front of them is like a broad-minded and amiable old man, always opening his arms so quietly and peacefully. At dawn, the old stork hovered in the air at the top of the big locust tree, singing in his throat. When the sun goes down, they eat the old nest and feed their children. In the dead of night, a deep, warm and sweet cry came from the old stork's nest. People are moved by the scenery, and people are compared with trees and birds. They were deeply moved: "Old storks still have nests to go back to, birds can be reunited with their families, but we can't go home, so we have to leave our hometown and live in another country." The ancient locust has a heartless lover, while the old stork has a nest and no family. They want to see, listen and think, if only people were old storks! At this time, it would be great if the locust tree could become a miraculous fairy, turn people into old storks, take shelter from the wind and live safely!
