This is a poem about homesickness, which is the source of China's poems about travel and travel. Looking at Danggui from a distance, looking up at the countryside, singing Long song and crying, is deeply moving.
In the poem, relatives remind me in my ear that the dreamland blends imagination and memory.
His father's "unfinished business" told him not to stay anywhere else forever. This tone is purely based on the son, without losing his father's broadmindedness, and his love for his son is deep and sincere.
I expressed my thoughts about my father, but I also saw his deep affection.
