In fact, most of the literary works we are familiar with about homesickness are domestic, but we may not be very familiar with the western literary works about homesickness. I personally learned the Odyssey in Homer's epic in a foreign literature class some time ago, only to find that this work involves homesickness.
Homer's epic is a great epic, including Iliad and Odyssey. According to legend, this epic was written by Homer, a blind poet in ancient Greece, so I won't study it here. The Iliad mainly describes a famous battle, the Trojan War. Interestingly, it was the ten-year war triggered by robbing women, and the content was wonderful.
The Odyssey, however, tells the story of Odysseus, the god of war, who went through hardships after the war and drifted at sea for ten years, and finally returned to his hometown, killing the suitor who invaded his palace and courted his wife, and reuniting with his wife and children. Odysseus went through all the hardships just to return to his hometown to reunite with his wife and children. His spirit touched the gods on Olympus, so they helped Odysseus go home. Although he experienced a series of hardships, Odysseus' firm belief in returning home remained unchanged, which was particularly touching.
