Why should the word "fu" be posted backwards?

"Dao" sounds like "here", which means to come in harmony. Sticking the word "Fu" in the Spring Festival, whether now or in the past, has pinned people's longing for a happy life and wishes for a better future. In order to fully reflect this yearning and wish, the people in China simply reversed the word "Fu", indicating that "Fu has fallen" and "Fu has arrived".

It is said that the custom of posting the word "Fu" upside down came from Gongwangfu in Qing Dynasty. On the eve of the Spring Festival one year, in order to please his master, the butler wrote many words of "Fu" as usual, which people posted on their warehouses and gates. A family member mistakenly pasted the word "Fu" on the gate because he could not read. To this end, Prince Gong Fujin was very annoyed.

Thanks to the eloquence of the official, he knelt on the ground and said, "I have often heard that Prince Gong lives a long life and is rich and magnificent. Now Dafu has really arrived, which is a good omen." Fujin thought after listening, no wonder passers-by said that Prince Gong's family was blessed (part two). He said auspicious words a thousand times, and gold and silver increased. When he was happy, he rewarded the housekeeper and blessed his family.

Later, the custom of posting the word "Fu" upside down was introduced to the people's homes from the top of the government. Everyone hoped that passers-by or urchins would say a few words: "Fu has arrived, Fu has arrived!"
