Wang Chunshi's first couplet is lyrical by borrowing scenery. Can you tell me specifically what the poet feels?

The old country is dead, only the mountains and rivers remain the same. Spring is lonely, and the deserted city is overgrown with vegetation.

The poet witnessed Chang 'an flute falling in autumn and homesick in adversity, and he couldn't help feeling deeply. Three or four couplets are about relatives, full of feelings of separation.

The whole poem is calm, sincere and natural, which embodies the poet's love for the motherland and his family. Today, Xu Yingpei and Zhou Rongquan commented on this poem: "The meaning is straightforward, the scenery is not free, the feelings are strong but not shallow, the things are rich but not miscellaneous, and the meter is rigorous but not rigid." This theory is quite appropriate. "A letter from home is worth a thousand pounds of gold" is also a famous saying that has been passed down through the ages.
