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.

百年好合 is a wish or greeting, often heard at Chinese weddings, for a couple to have 100 good years together.

Some will translate this more naturally into English as: “May you live a long and happy life together.”

The character breakdown:
百 = 100
年 = Years
好 = Good (Happy)
合 = Together

不管黑猫白猫能捉着老鼠的就是好猫 literally translates as: It doesn't matter [if a] cat [is] black [or] white, [as long as it] can catch mice, it's a good cat.

This proverb was either composed or made famous by Deng XiaoPing in 1961 when he exclaimed, “I don't care if it's a white cat or a black cat. It's a good cat so long as it catches mice” when his critics pointed out that his ideas were Capitalistic (free market). The response was meant to say, “It does not matter if it's Communist or Capitalist, as long as it works.”

This is a Chinese proverb that can be used to suggest one should disregard looks or a person's race, as long as they can do the job. It can also be used as a metaphor for many other situations.

Deng XiaoPing probably saved China from collapse (as the Soviet Union experienced). He changed China’s economy from pure Communism to a hybrid where the free market (Capitalism) is encouraged. More about Deng XiaoPing

同心協力 is a Chinese proverb that means “to work with a common purpose,” “to make concerted efforts,” “to pull together,” or “to work as one.”

This proverb can be translated as “Cherish Time as if it was Gold” or “Time is as Valuable as Gold.”

This basically suggests that time is gold, and you should value the time you have (and use it well).

春宵一刻 is a Japanese proverb that means “A moment of time in a spring evening (is worth a thousand pieces of gold).”

百聞不如一見 is a Chinese proverb that means “Seeing once is better than hearing one hundred times” which is similar to the idea of “Seeing is believing.”

You can also get the idea, “Seeing for oneself is better than hearing from many others.”

If you break it down directly, you get “100 hears/listens (is) not as-good (as) one sight.”

白酒紅人面黃金黑世心 literally says: [Just as] white liquor makes people's faces turn red, [So] yellow gold makes people's hearts turn black.

This is a warning about the nature of greed. The suggestion is that one who lusts for gold and riches will eventually have a black heart (or become a heartless greedy bastard). As a wall scroll, this is a reminder and warning to keep yourself from following the greedy path.

面壁九年 is a Buddhist term that means “facing a wall for nine years.”

This refers to the Bodhidharma who stared at a wall in meditation at the Shaolin Temple (or in a cave) for nine years until reaching full enlightenment.

視卒如嬰兒故可以與之赴深溪視卒如愛子故可與之俱死 is an entry from the 10th section within the Earth/Terrain chapter of Sun Tzu's Art of War.

This is often translated as “Regard your soldiers as your children, and they will follow you into the deepest valleys. Look upon them as your own beloved sons, and they will stand by you even unto death.”

行百里者半九十 is an old Chinese proverb that speaks to the act of giving up. This phrase suggests that no matter how close you are to finishing your task or journey, giving up just before you finish is just as bad as giving up halfway.

50% finished or 90% finished, the result is the same: “You are not finished.”

You can take what you want from this proverb, but I think it suggests that you should finish what you start, and especially finish that last 10% of your journey or project so that you can honestly say “it's finished.”

Some notes: The character, 里, that I am translating as “mile” is an ancient “Chinese mile” which is actually about half a kilometer - it just doesn't sound right to say “When walking 100 half-kilometers...”

武士の一言金鉄の如し is an old Japanese proverb about the value of the word of a warrior.

Here are a couple of versions of how this can be translated:

A warrior's single word is as unchanging and reliable as gold and steel.
A warrior's promise is as dependable as gold, and his [scabbard contains] untarnished steel (a sword).

Note: Sometimes this phrase is written as 男子の一言、金鉄の如し (danshi no ichigon kintetsu no gotoshi)

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

一致団結 is a Japanese phrase that means solidarity, or “banding together and working as one for a common cause.”

不怕人老只怕心老 literally translates as: Do not be concerned about being old; be concerned about a mind which is old.

Figuratively, this means: You are not as old as you look, you are only as old as you think you are.
