Lioness in Chinese / Japanese...

雌獅 is how to write “lioness” in Chinese.

Note: 雌獅 is not a very common title for a wall scroll in China. Perhaps because lions are not indigenous to China. Though oddly enough, the rarity of lions made them very prized - and lion dances are a popular festival attraction.
If you see the name of this animal species written on a wall scroll, it's more likely to be the masculine form of “lion.”

河東獅吼 is actually a proverb and joke about the plight and fear of a hen-pecked husband.

In ancient times, it was used to describe a wife who would berate her husband or go into jealous rages. However, this phrase currently brings about ideas of a husband that cowers in fear and cringes when his wife screams (or roars) at him.

Please only purchase this as a good-natured joke. If your wife or husband does not have a good sense of humor, it's probably not a good idea to hang this on your wall to irritate your mate.
