Yuan in Chinese / Japanese...

媛 means, a beauty; beautiful (woman); princess; a young lady of noble birth; girl; small & lovely.

媛 is used a bit more commonly in Chinese than in Japanese.

Note: This can be the female given name "Hime" in Japanese.

緣 represents the fate that brings and bonds people together.

緣 is a complicated single character. It can mean a lot of different things depending on how you read it.

In Japanese, it can mean fate, destiny, a mysterious force that binds two people together, a relationship between two people, bond, link, connection, family ties, affinity, opportunity, or chance (to meet someone and start a relationship). It can also mean “someone to rely on,” relative, reminder, memento, or the female given name, Yori.

It's the same in Chinese, where it's defined as cause, reason, karma, fate, or predestined affinity.

In the Buddhist context, it's Pratyaya. This is the concept of indirect conditions, as opposed to direct causes. It's when something happens (meeting someone) by circumstance or a contributing environment. Instead of a direct cause or act, it is a conditioning cause without direct input or action by the involved people.

Occasionally, this character is used in a facetious way to say hem, seam, or edge of clothing. In this case, it's the seam that brings or holds the clothing together.

Note: Japanese will tend to use the variant of this Kanji shown to the right. If you want this version (and are ordering this from the Japanese master calligrapher), click on the Kanji at the right instead of the button above.

園 is a single character that means garden in Chinese, Japanese Kanji, and old Korean Hanja.

This can also mean an orchard or park.

園 is not a common single character for a wall scroll but nothing is wrong with it. A lot of customers asked for a single character for a garden, so I've provided what I think is the best option here.

猿 is one of those cases when an error was made as Chinese characters were absorbed into the Japanese language during the 5th century.

In Japanese, this means monkey.
In Chinese, this means ape.

The Japanese word for ape means monkey in Chinese, so you can see how they were simply reversed.

黿 is the Chinese and Korean title for sea turtle.

黿 may also be used to refer to a loggerhead turtle or hawksbill turtle.

円 is Yen, the Japanese currency.

円 is the Japanese variant of the original Chinese 圓 or 圆. It means circle, entirety, whole, full, or complete. It was the slang usage that became money, dough, or moola.

Occasionally, this is used as a given name or for other interesting uses. This version of the character is seldom used in Chinese unless referring to Japanese money.

Unless you have a specific reason to request it, this is a strange selection for a wall scroll.
