Second, homesickness
1. Homesickness is an emotional state of attachment to hometown. Attachment to the homeland is the same and eternal emotion of human beings. Wanderers, drifters, vagrants and immigrants who are far away from home will miss their hometown; Homesickness or homesickness refers to "the pain a sick person feels because he is not in his hometown" or "the fear of never seeing his hometown again"
2. Homesickness is no longer a medical disease, but it still has very real physiological symptoms in essence. These symptoms may be, but are not limited to: chest tightness, tight throat, chest pain, and will cause despair.
Third, expand
Homesickness is sometimes like an epidemic. In the army, homesickness is less common when you win a battle. On the contrary, homesickness is more common when the war is tight. In the Chu-Han War in history, Xiang Yu and his army fell into a trap. China soldiers sing Chu songs in order to arouse Chu troops' homesickness and disintegrate their fighting capacity, which is the origin of China's idiom "besieged on all sides".
