The name Sailing Boat in Chinese / Japanese...

刻舟求劍 is an originally-Chinese proverb that serves as a warning to people that things are always in a state of change.

Thus, you must consider that and not depend on the old ways or a way that may have worked in the past but is no longer valid.

This idiom/proverb comes from the following story:
A man was traveling in a ferry boat across a river. With him, he carried a treasured sword. Along the way, the man became overwhelmed and intoxicated by the beautiful view and accidentally dropped his prized sword into the river. Thinking quickly, he pulled out a knife and marked on the rail of the boat where exactly he had lost his sword.

When the boat arrived on the other side of the river, the man jumped out of the boat and searched for his sword right under where he'd made the mark. Of course, the boat had moved a great distance since he made the mark, and thus, he could not find the sword.

While this man may seem foolhardy, we must take a great lesson from this parable: Circumstances change, so one should use methods to handle the change. In modern China, this is used in business to mean that one should not depend on old business models for a changing market.

This proverb dates back to the Spring and Autumn period (770–476 BC) of the territory now known as China. It has spread and is somewhat known in Japan and Korea.

不會撐船賴河灣 literally translates as: [One who] cannot steer the boat blames the bends in the river.

Figuratively, this means: One who is incompetent always tries to shift the blame elsewhere.
This is similar to the English idiom, “a poor workman/craftsman blames his tools.”

Many things have opposite properties. The water you drink can also drown you. Pork may nourish you and keep you alive but under-cook it and it could kill you. Potassium nitrate is often used as a fertilizer to grow the food that sustains us but it's also been used as an explosive to topple buildings and destroy us.

This concept is easily associated with “yin yang” where an element has two opposite properties that are as different as night and day.

This proverb's meaning can be summed up this way: “Anything that can lead you to success may also contain great risks.”

This phrase is known in literary circles by Korean people (scholars or literature). It is therefore also a valid proverb in Korean Hanja, though most Koreans would not be able to make sense of it.

Please note that there is an unwritten rule when the same character appears twice in the same phrase, the calligrapher will alter the appearance so that no two characters are exactly alike in the same piece. This calligraphy has two repeating characters that will be written differently than they appear here.

一帆風順 is just what you think it means. It suggests that you are on a trouble-free voyage through life, or literally on a sailing ship or sailboat. It is often used in China as a wish for good luck on a voyage or as you set out on a new quest or career in your life. Some may use this in place of “bon voyage.”

The literal meaning is “Once you raise your sail, you will get the wind you need, and it will take you where you want to go.” Another way to translate it is “Your sail and the wind follow your will.”

This is a great gift for a mariner, sailor, adventurer, or someone starting a new career.

Note: Can be understood in Korean Hanja but is rarely used.
