Five Blessings

I found online an explanation of the stamp:

The Chinese character "Fu" (meaning "blessing") is used to express people's longing for a happy life and their wish for a better future. Against the simple white background of the stamp, the four bats (the Chinese character for bat is the same as the Chinese character for blessing) combined with the golden character "Fu" in the middle of the stamp cleverly express the meaning of "five blessings come to your door".
