What's the significance of posting blessings during the Spring Festival?

Some blessings can't be posted, but only one can be posted by the lucky people. Pay attention to the time of posting the blessing, and the blessing on the gate should be posted immediately.

Among them, there is the blessing of "long life" written by Emperor Kangxi, and the blessing of "peace and prosperity" which is more popular recently. There is no seal at the bottom of the blessing, and it is easy to form a fierce word when it is pasted upside down. Sending too many blessings is called "repeating the same mistakes" unlucky. The gate is a place to welcome blessings, so the word "Fu" must be posted on the gate, which means to open the door to welcome blessings.

Happiness has four meanings: one is "longevity", that is, longevity and longevity; The second is "wealth", that is, wealth is abundant; The third is "Kangning", that is, healthy and disease-free; The fourth is "virtue and goodness", that is, virtue and goodness have good ways.
