First of all, if you want to deduct Jiangnan from the perspective of flowers, then the flower specificity written must not be found elsewhere, at least it can make people think of Jiangnan immediately (such as the scenery with flowers); Secondly, since we are writing about the flowers in the south of the Yangtze River, we should have the characteristics of the south of the Yangtze River, which can be cut from two aspects: nature (such as rain) and humanity (such as human feelings). Then, when writing the above two points, we should pay attention to comparing Tang poetry and Song poetry respectively. As for the last point, its purpose should be to spend it on the people of the two dynasties, because the ultimate goal or final reflection of the scene is still people; We should consider whether the chosen person can generally reflect the atmosphere of Tang poetry and Song poetry. For the purpose of writing structure, we can put this point in the second place. At this time, Li Qingzhao and Bai Juyi's Flowers were only used as an example to improve their level.
