No More Fear in Chinese / Japanese...

勇敢 is about courage or bravery in the face of fear.

You do the right thing even when it is hard or scary. When you are courageous, you don't give up. You try new things. You admit mistakes. This kind of courage is the willingness to take action in the face of danger and peril.

勇敢 can also be translated as braveness, valor, heroic, fearless, boldness, prowess, gallantry, audacity, daring, dauntless, and/or courage in Japanese, Chinese, and Korean. This version of bravery/courage can be an adjective or a noun. The first character means bravery and courage by itself. The second character means “daring” by itself. The second character emphasizes the meaning of the first but adds the idea that you are not afraid of taking a dare, and you are not afraid of danger.

勇敢 is more about brave behavior and not so much the mental state of being brave. You'd more likely use this to say, “He fought courageously in the battle,” rather than “He is very courageous.”

百折不撓 is a Chinese proverb that means “Be undaunted in the face of repeated setbacks.”

More directly translated, it reads, “[Overcome] a hundred setbacks, without flinching.” 百折不撓 is of Chinese origin but is commonly used in Japanese and somewhat in Korean (same characters, different pronunciation).

This proverb comes from a long, and occasionally tragic story of a man that lived sometime around 25-220 AD. His name was Qiao Xuan, and he never stooped to flattery but remained an upright person at all times. He fought to expose the corruption of higher-level government officials at great risk to himself.

Then when he was at a higher level in the Imperial Court, bandits were regularly capturing hostages and demanding ransoms. But when his own son was captured, he was so focused on his duty to the Emperor and the common good that he sent a platoon of soldiers to raid the bandits' hideout, and stop them once and for all even at the risk of his own son's life. While all of the bandits were arrested in the raid, they killed Qiao Xuan's son at first sight of the raiding soldiers.

Near the end of his career, a new Emperor came to power, and Qiao Xuan reported to him that one of his ministers was bullying the people and extorting money from them. The new Emperor refused to listen to Qiao Xuan and even promoted the corrupt Minister. Qiao Xuan was so disgusted that in protest, he resigned from his post as minister (something almost never done) and left for his home village.

His tombstone reads “Bai Zhe Bu Nao” which is now a proverb used in Chinese culture to describe a person of strong will who puts up stubborn resistance against great odds.

My Chinese-English dictionary defines these 4 characters as “keep on fighting despite all setbacks,” “be undaunted by repeated setbacks,” and “be indomitable.”

Our translator says it can mean “never give up” in modern Chinese.

Although the first two characters are translated correctly as “repeated setbacks,” the literal meaning is “100 setbacks” or “a rope that breaks 100 times.” The last two characters can mean “do not yield” or “do not give up.”
Most Chinese, Japanese, and Korean people will not take this absolutely literal meaning but will instead understand it as the title suggests above. If you want a single big word definition, it would be indefatigability, indomitableness, persistence, or unyielding.

布施 is the Buddhist practice of giving known as Dāna or दान from Pali and Sanskrit.

Depending on the context, this can be alms-giving, acts of charity, or offerings (usually money) to a priest for reading sutras or teachings.

Some will put Dāna in these two categories:
1. The pure or unsullied charity, which looks for no reward here but only in the hereafter.
2. The sullied almsgiving whose object is personal benefit.
The first kind is, of course, the kind that a liberated or enlightened person will pursue.

Others will put Dāna in these categories:
1. Worldly or material gifts.
2. Unworldly or spiritual gifts.

You can also separate Dāna into these three kinds:
1. 財布施 Goods such as money, food, or material items.
2. 法布施 Dharma, as an act to teach or bestow the Buddhist doctrine onto others.
3. 無畏布施 Courage, as an act of facing fear to save someone or when standing up for someone or standing up for righteousness.

The philosophies and categorization of Dāna will vary among various monks, temples, and sects of Buddhism.

Breaking down the characters separately:
布 (sometimes written 佈) means to spread out or announce, but also means cloth. In ancient times, cloth or robs were given to the Buddhist monks annually as a gift of alms - I need to do more research, but I believe there is a relationship here.
施 means to grant, to give, to bestow, to act, to carry out, and by itself can mean Dāna as a single character.

Dāna can also be expressed as 檀那 (pronounced “tán nà” in Mandarin and dan-na or だんな in Japanese). 檀那 is a transliteration of Dāna. However, it has colloquially come to mean some unsavory or unrelated things in Japanese. So, I think 布施 is better for calligraphy on your wall to remind you to practice Dāna daily (or whenever possible).
