What is the general meaning of Su Shi's Haitang and the poet's emotion?

Emotion: using personification, metonymy and other rhetorical devices (red makeup refers to women), write that the color, fragrance and taste of Haitang are real, and the expression of Haitang is empty, combining reality with reality. Expressed the poet's love and cherish for flowers. General idea: the spring breeze gently blows the begonia, and the flowers bloom wonderfully. The hazy night fog was full of flowers, and the moonlight turned the cloister upside down. It was late at night, and I was worried that Haitang would fall asleep like a human being, so I quickly lit a candle and shone it on Haitang.
