Still Heart in Chinese / Japanese...

關心 means caring in Chinese.

Caring is giving love and attention to people and things that matter to you and anyone who needs help. When you care about people, you help them. You do a careful job, giving your very best effort. You treat people and things gently and respectfully. Caring makes the world a safer place.

Note: 關心 is also a word in Korean Hanja, but in Korean, it means taking interest or concern. In Korean, it's still a good word, but it doesn't quite have the “caring for a person” meaning that it does in Chinese.

專心 makes a word that means “paying attention with your heart.”

It's often translated as “dedication,” as in “be absorbed in” or “concentrate one's efforts.” It's also used to mean “with the single mind,” “whole-heartedly,” “paying attention,” “undivided attention,” “concentration (-ed),” “engrossed,” “devotionally (listening/watching),” and/or “attentive.”

The first character means “for a particular person, occasion, or purpose,” “focused on one single thing,” “concentrated,” and sometimes, “special.”

The second character means “heart” or “mind” by itself.

My favorite translation, which comes from the Oxford Advanced Chinese/English Dictionary, is, “wholehearted devotion.”

If it seems like the meaning of this word is quite open, you are correct. The context in which the word is used matters a lot. It can mean different things depending on how you use it. This makes it kind of nice as you can decide what this means to you (within some limits). This is always positive in meaning, so even if a Chinese person reads it differently than you, it will still have a good meaning.

In Japanese, they tend to use a variation of the second character which has one less stroke. If you want your calligraphy written this Japanese form, please click on the Kanji shown to the right instead of the button above. Note: Japanese and Chinese people will recognize either form.

我心真愛 is a slightly poetic way to express this sentiment to someone.

The meaning is “My True Love,” but the characters directly translate as “I/Me/My Heart/Mind True/Real Love.”

Note that Chinese grammar and construction are different, so this sounds very eloquent and artsy in Chinese.
In Korean Hanja, the third character should be written differently. Just let me know when you place your order if you want that version - it will still make sense in Chinese. This phrase makes sense in Korean but is not commonly used.
