What does it mean that flowers are similar year after year and people are different year after year?

Flowers are similar year after year, but different people mean that flowers are the same year after year, while people who look at flowers year after year are different.

Source: A Generation of Sad Pulsatilla by Liu Xiyi in the Tang Dynasty: "The ancients have not recovered from Luocheng East, but today people are still disappointed. Flowers still bloom every year, but they are different every year. Tell those young people in their prime that they should pity this half-dead old man. Unfortunately, the old man is bald. Yi is a beautiful young man. "

Old friends no longer lament the withering of peaches and plums in the east of Luoyang, and now people are still sad for the falling flowers falling with the wind. Flowers still bloom every year, but people who look at them every year are different.

Tell those young people in their prime to pity this half-dead old man. Now his hair is all white, poor thing. However, he used to be a charming young man.

Appreciation of Pulsatilla Generation North:

"The ancients have never recovered from Luocheng East, but today people are still disappointed" in Pulsatilla Generation reveals the objective law that life is perishable and the universe is eternal. The phrase "flowers are similar year after year, people are different year after year" expresses the sigh that youth is easy to get old and things are impermanent with beautiful, smooth and neat antithesis, and is full of poetic artistic conception and philosophy.

By describing Pulsatilla's life from beauty to old age and illness, from amusement to loneliness, it not only expresses the poet's attachment and yearning for youthful beauty and singing and dancing, but also expresses his pity and sympathy for the elderly Pulsatilla, further expressing his feelings about the shortness of beauty and limited life, thus enhancing the artistic appeal and philosophy of poetry.
