Excuse me, what are the meanings of "green sunflower burning clouds" and "yellow flowers in the evening" in the four-character life?

Bibi brand cloud: Bibi: for example; Hey, an ancient gibbon; "Branding" is the word "fishing" commonly used in ancient times.

This sentence means: just like an ape fishing for clouds, it means "monkeys fishing for the moon", and numerology means that the career will end in vain.

Pronunciation w m:n Jie Huáng Huā

Interpretation of yellow flowers: chrysanthemum; Evening festival: moral integrity in later years. Metaphor is noble at night.

Song Hanqi's poem "Jiutian Pavilion" originated from: "Don't think that the autumn color of the old nursery is pale and the yellow flowers are seen at dusk."

An example must go through difficulties and obstacles. ("Wang Ming's Poetry" Volume 38)

The above is my explanation based on ancient books, please indicate the quotation. Thank you.
