Wufu - five bats decoration

I am looking for illustrations of Chinese porcelain decoration of 'wufu' or bats. On another site I came across a description describing the importance of bats in Chinese mysticism:

BAT - Emblem of happiness. Usually painted red, the colour of joy. The Wu Fu, or five bats of happiness, stand for the five blessings: old age, wealth, health, virtue and natural death.

Wufu decoration is apparently used extensively by the Chinese in decoration of all sorts, especially porcelain.

I would be most thankful if you could advise of a website or source that could provide some illustrative reference.

A iron red Wufu Imperial Daoguang dish

Here are two pictures of the best example of "wufu" = five happinesses decoration I have come across.

The dish is a Daoguang 1821 - 1850 Imperial mark and period dish.

Thank you for your interest.

Best regards,
