Green in Chinese / Japanese...

青 is nature's color and can refer to forest green, greenish-blue, or the darkest of greens.

青 and color represent nature, youth, and young people.

In the same way, we refer to green bananas and the rookie being green, the same is true in Chinese and Japanese, where, in a certain context, this can mean immature, unripe, or young.

In Japan, this can also be a female given name “Haru.” It can also be used as a given name (for either sex) in China.

爐火純青 means “[The] furnace fire [has become] pure green.

This is an allusion to Daoist alchemy. figuratively, this speaks of an art or technique brought to the point of perfection.

青梅竹馬 means “green plums and hobby-horse.”

Figuratively, it means “innocent children's games,” “childhood sweethearts,” or “a couple who grew up as childhood friends.”

This phrase may sound a little strange as it's a kind of Chinese proverb or idiom. It makes much more sense in Chinese than in English.

靑龍 is a title that can mean blue or green dragon.

The first character can mean blue, green, azure, or celadon.

The second character means dragon.

This is mostly a Chinese title (especially in Buddhism). It will be understood but less commonly used in Japanese and Korean.

翠鳥 is the title for the kingfisher bird in Chinese.

翠 means bluish-green or green jade.

鳥 means bird.

怡紅院 is from “The Story of the Stone” by Cao Xueqin.

For some reason, this phrase was translated as “House of Green Delights” when the novel was published in English. The translator took some liberties and believed that “green” had a more positive feel than red to a western audience. Therefore, the phrase shown to the right is “House of Red Delights” (which is the most original and correct way).

青玉 is a Japanese word that means sapphire or jacinth.

青玉 literally means blue/green jade.

Note: This also makes sense in Chinese, but will be read as "blue jade", rather than being understood to be sapphire (藍寶石 is sapphire in Chinese).

碧 is a common transliteration to Mandarin Chinese for the name Bee.

This has nothing to do with the insect bee. The meaning of the character is actually “fresh and green.”

獅子舞 is the Japanese title for lion dancing.

This refers to the Japanese version borrowed from traditional Chinese culture. The Japanese version almost always features a red-faced lion with a green cloak with a white pattern.

蒼龍 is one of a couple of possible titles for “blue dragon” (occasionally also translated as “green dragon”).

The first character means “deep blue” or “azure.”

The last character is dragon.

蘋果 is the Chinese word for Apple.

This red or green fruit tree grows well in the cool winter climates of northern China.

In the context of computers and smartphones, this can refer to Apple Computers.

青色 is a Chinese word that is used for the color cyan.

This can also refer to a blue-green color.

In Japanese, this is an alternate way to refer to a blue color.

玉 is how to write jade in Chinese, Korean Hanja, and Japanese Kanji. This refers to the semi-precious stone that can be almost white or a vivid green.

Note: In Japanese, this character can mean jewel, ball, sphere or coin depending on context.

If your name is Jade, you may want to choose this to represent your name by meaning rather than pronunciation.

羅剎 is the Chinese version of demon that comes from the ancient Sanskrit word raksha, raksasa (rākṣasa), raksas (rakṣas), or raksasi (rākṣasī).

This title regards malignant spirits and demons. These demons are described in ancient texts as terrifying, with black bodies, red hair, and green eyes, and as devourers of men.

FYI: Sometimes the second character is written in the form shown to the right.

真主 is how Chinese Muslims refer to God (it literally means “True Master”).

Oddly, in China, two different names for God have emerged. Even though Muslims, Christians, and Jews all worship the same God of Abraham.

In Arabic, the word Allah is just the Arabic way to say, God. Arab Christians pray to Allah, just like Arab Muslims. Somehow in China, the title of God diverged.

If you are curious, there are millions of Muslims throughout China but especially in the northwest portion of China known as Xinjiang. Here you will find descendants of Turkmen, Persian, Arab, and other ethnicities. Some are mixed with Han-Chinese blood; others appear to be pure Turkmen. Many have fair complexions, green eyes, and light hair but all are citizens of China. A visit to Xinjiang will shift your paradigm and blow away all of your stereotypes about what it means to be Chinese.

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).
