巾幗 is the very old way to say woman in Chinese.

A common title in ancient China, this actually refers to the scarf or head wrapping worn by virtually all women at that time.

巾幗 is kind of a cool way to say Woman now. The actual gender character alone on a wall scroll would actually look like a fancy sign for the woman's restroom (WC).
If you are curious, the character to the right means female or woman. Knowing 女 is useful information if you are a woman searching for a toilet in China or Japan.

盡忠報國 is a proverb that is the tattoo worn on the back of Yue Fei, a famous Chinese warrior who lived until 1142 A.D.

The tattoo can be translated as “Serve the country with the utmost loyalty.” More literally, it means “[The] Ultimate Loyalty [is too] Duty [of] Country.”

Legend has it that this tattoo once saved his life when he was accused of treason.

The first two characters have come to create a word that means “serve the country faithfully” or “die for the country.” Note: It's more a willingness to die for one's country than the actual act of dying.

The last two characters have come to mean “Dedicate oneself to the service of one's country.”

Both of these words are probably only in the Chinese lexicon because of this famous tattoo.

If you break it down, character-by-character, here is what you get:
1. To the utmost, to the limit of something, the ultimate.
2. Loyalty or duty (a sense of duty to one's master, lord, country, or job).
3. Report, recompense, give back to (in this case, you are giving yourself to your country as payback).
4. Country, state, nation, kingdom.
