Wei Zi's couplet video

Answering your question involves a lot of couplet common sense.

(1) "Purple gas comes from the east" is a fixed phrase and cannot be changed at will. Contrary to this idiom, "purple" is a color word and "east" is a position word. You must use words like "White clouds go west."

(2) It can be seen that the purple gas from the east and Fuxing are shining high and cannot be relative. Either change the first sentence or change the last sentence. If you don't change it, it will be a mistake! The patchwork stickers on the door should have nothing to do with the expected auspiciousness. Be careful what you say.

(3) People don't have to write couplets with such tall words. Simplicity can also be regarded as wisdom. You only change two sentences in your couplets for reference.

Part I: Jubao Yuan Di is small and ambitious.

Bottom line: building a Chinese guild hall is low in ambition and high in ambition.
