Fall Down Seven Times Get Up Eight in Chinese / Japanese...

七転八起 is a Japanese proverb that relays the vicissitudes of life, with the meaning “seven times down eight times up.”

Some would more naturally translate it into English as “Always rising after a fall or repeated failures” or compare it to the English, “If at first, you don't succeed, try, try again.”

The first Kanji is literally “7.” The second means “fall down” (sometimes this Kanji means “turn around,” “revolve” or “turn over” but in this case, it holds the meaning of “fall”). The third is “8.” And the last is “get up,” “rouse,” or “rise.”

Basically, if you fail 7 times, you should recover from those events and be prepared to rise an 8th time. This also applies if it is the world or circumstances that knock you down seven times...
...just remember that you have the ability to bounce back from any kind of adversity.

Note: This can be pronounced in two ways. One is “shichi ten hakki” or “shichitenhakki.” The other is “nana korobi ya oki” also written, “nanakorobi-yaoki.”

Special Note: The second character is a Kanji that is not used in China. Therefore, please select a Japanese calligrapher for this title.

百胜难虑敌三折乃良医 is a Chinese proverb that literally translates as: [Even a general who has won a] hundred victories [may be] hard put to see through the enemy's [strategy], [but one who has] broken [his] arm three [times] [will] be a good doctor.

Figuratively, this means: One cannot always depend on past successes to guarantee future success but one can always learn from lessons drawn from failure.

一日千秋 is a Japanese and Chinese proverb about missing someone.

一日千秋 is often used to express how hard it is to wait for someone's return or to be away from someone.

Some will translate this as “one day feels like a very long time” or “waiting for someone (something) is hard.”

You might see this romanized as a single word, Ichijitsusenshuu, or as “Ichijitsu Senshuu” from Japanese.
If you break down the characters one-by-one, we get:
一 = one/a
日 = day/sun (can also represent time or date)
千 = 1000/thousand
秋 = autumn/fall

Together, 千秋 can mean “autumn comes thousand times” (or 1000 years). It can also be read as 1000 periods of time.
However, it relays the idea of heartache as you wait for someone you miss.
