Adorable Cute Lovely in Chinese / Japanese...

可愛い is a Japanese word that means cute, adorable, charming, lovely, or pretty.

Depending on the context, it can also mean dear, precious, darling, pet, cute little, or tiny.

可愛 is a Chinese word that means adorable, cute, and lovely.

It also has a similar meaning in Japanese, but it's more often used as the given name Kawai.

In the Buddhist context, it can mean agreeable.

The meanings for 妙 include: clever; wonderful; strange; unusual; superb; excellent; beautiful; mystic; supernatural; profound; mysterious; good; surpassing; fine, lovely, charming; special; outstanding; incomparable.

As you can see, this single character can mean a lot of things (a bit ambiguous).

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.

可愛い子には旅をさせよ is a Japanese proverb that means “If you love your children, send them out on a journey into the world.”

This is kind of similar to the western phrase, “Spare the rod and spoil the child.”

More literally, this reads, “Cute child, a journey granted.”
That “granted” could also be understood as “should be initiated.”

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

甘味 is sweet or sweetness in Chinese characters, Japanese Kanji, and old Korean Hanja. This refers to a sweet taste, sugary taste, or sweet flavor. It can also be a noun meaning sweets, dessert, or cake.

This can also refer to charm or appeal (of a woman or lovely thing).

素敵な偶然 is a common way to express serendipity in Japanese.

The first two characters mean nice, lovely, dreamy, beautiful, great, fantastic, superb, or cool.

In the middle is a Japanese Hiragana character connecting these words/ideas.

The last two Kanji mean incidentally, by chance, randomly, unexpectedly, suddenly, accident, fortuity, or by coincidence.

美麗 is a two-character word used often in Chinese, old Korean, and ancient Japanese to express beauty.

I've had a few requests for a “two-character beautiful,” and this is by far the best word. This is not a common word for an Asian person to want on a wall scroll. However, you will see it commonly used as an adjective in phrases, stories, and titles throughout magazines and signage in China.

美麗 can also be translated as gorgeous or lovely.

Note: 美麗 is not commonly used in modern Japan.

誰言寸草心報得三春暉 is the last line of a famous poem. It is perceived as a tribute or ode to your parents or mother from a child or children that have left home.

The poem was written by Meng Jiao during the Tang Dynasty (about 1200 years ago). The Chinese title is “You Zi Yin” which means “The Traveler's Recite.”

The last line as shown here speaks of the generous and warm spring sunlight which gives the grass far beyond what the little grass can could ever give back (except perhaps by showing its lovely green leaves and flourishing). The metaphor is that the sun is your mother or parents, and you are the grass. Your parents raise you and give you all the love and care you need to prepare you for the world. A debt that you can never repay, nor is repayment expected.

The first part of the poem (not written in the characters to the left) suggests that the thread in a loving mother's hands is the shirt of her traveling offspring. Vigorously sewing while wishing them to come back sooner than they left.
...This part is really hard to translate into English that makes any sense but maybe you get the idea. We are talking about a poem that is so old that many Chinese people would have trouble reading it (as if it was the King James Version of Chinese).
