What does "preparation" mean in the Book of Songs of "Love in a Fallen City"

"The Book of Songs Tang Feng Preparation":

Three stars are in the sky when you prepare for the firewood. What night is this? See this good man. Zi Xi Zi Xi! What a good man!

Three stars are in the corner. What night is this? See this encounter. Zi Xi Zi Xi! What an unexpected encounter!

Take care of Chu, and have three stars at home. What night is this? See this charming person. Zi Xi Zi Xi! Who is so charming!

This is a poem about happy newlyweds. The poet felt that his bride was indescribably beautiful, and that night was also indescribably beautiful. I am so happy about this good day that I simply don’t know what to do (overjoyed). "The Book of Songs" often talks about the marriage of men and women and "salary", such as "Han Guang" "Qiaoqiao Wrong salary"; "Nanshan" "Analysis of salary like"; "Dongshan" "Hang Zai Li Xin"; "Che Ju" "Analysis of the firewood", "Bai Hua", "Qiaobi mulberry firewood", etc. are all. Here it is "preparing for the end of the year".

Note: 笍唰 (獯MU chóu móu): It means "lingering", meaning to bind tightly. The poet seems to use the metaphor of a lingering salary as a metaphor for marriage.
