Why does China's blessing stick backwards?

The word "fu" is now interpreted as "happiness", but in the past it meant "good luck" and "good luck". No matter now or in the past, the word "Fu" posted in the Spring Festival has pinned people's yearning for a happy life and wishes for a better future. In order to fully reflect this yearning and wish, the people simply turn the word "fu" upside down, and happiness has fallen to the word "fu". "There is also a legend that the word' fu' is posted upside down among the people. Ming Taizu used the word "Fu" as a code word to prepare for murder. In order to eliminate this disaster, the good-hearted horse queen asked all families in the city to put "Fu" on their doors before dawn. Naturally, no one dares to go against Ma Huanghou's will, so the word "Fu" is put on every door. If one family can't read, turn the word "fu" upside down. The next day, the emperor sent people to the streets to check and found that every family had posted the word "Fu", and another family had posted the word "Fu" upside down. When the emperor heard the news, he was furious and immediately ordered the body guard to cut down the house. Seeing that something was wrong, Ma Huanghou quickly said to Zhu Yuanzhang, "The family knew that you were visiting today and deliberately reversed the word' Fu'. Isn't that what "Fu" means? " When the emperor heard the truth and ordered his release, a catastrophe was finally eliminated. Since then, people have turned the word "Fu" upside down for good luck and in memory of Ma Huanghou.
