Some topics in Du Fu's poems are followed by the word "X", such as "My uncle's family in Baishui Mingfu loves the rain and got the word". What does "too much" mean here?

At banquets, impromptu propositions are the rules for writing poems. Assign a word to everyone, and then write a poem on the spot with the rhyme made by this word.

In the fiftieth chapter of A Dream of Red Mansions, there is a description of rhyming writing:

Baochai had to agree and added, "Let's use the word Hongmei as the rhyme, each with seven tones. Sister Xing is a scarlet letter, sister Li is a plum character, and the harp is a flower character. "

So the poems written by three people are: "Red" means Hongmei (Xing Xiuyan), "Mei" means Hongmei (Wenli) and "Flower" means Hongmei (Xue Baoqin).

Du Fu's poem should be a banquet ordered by Baishui County. Most of them found a poem or something on the spot, and everyone took turns to take a word from it as rhyme. Du Fu was given the word "Guo", so this poem he wrote used the rhyme of five songs where the word "Guo" was located.
