Jiaxu is a poem with many readers. My understanding is different from others. This is a poem that people sing when cutting reeds (otherwise, what does the poet do by the reed in the early morning? ), and "light" refers to light yellow. It's already late autumn when it's frosted, and reeds won't be lush any more. This is common sense; And "sadness" means dense, not lush; "Mining" refers to logging, which is synonymous with "mining".
The artistic features of "Jian Jia" are parallelism, orderly arrangement of sentence patterns, cadence of syllables and harmonious and beautiful melody throughout, and it is a rare masterpiece in China's poetry treasure house.
