Five Red Bats in Chinese / Japanese...

紅五蝠 is a play on words in Chinese because of some homophones.

The first thing you need to know is that the word for bat, 蝠, sounds exactly like the word for good fortune, 福. Thus, bats are often associated with good luck and good fortune in Chinese culture.

Five bats (五福 / 五蝠) means “five fortunes,” referring to luck, prosperity, wealth, happiness, and longevity.

The word red, 红, has the same sound as 宏 meaning vast, great, or magnificent. Therefore, a red bat means “vast fortune.”

Altogether, five red bats represent vast reaches of the five fortunes.
