美魂 is a very short or abbreviated way to say “Beautiful Soul” in Japanese.

There is a more extended version that might be a little more natural and also closer to the intended meaning. This short title is often translated awkwardly as “Beauty Soul” in Japanese.

髮狂 is the nicest/coolest way to write “crazy” in Chinese.

There are several other ways to express “insane” or “mentally disturbed,” but they are either clinical terms or very serious afflictions.

髮狂 is not a great or normal selection for a wall scroll. Please only order this if you want this idea for some personal reason.

To put it another way: It's a little crazy to have a “crazy” wall scroll.

詠春 is a martial arts technique that has an oral history (versus a written one) so very little can be said for sure about its origins.
Wing Chun (or Wing Cheun) is a Chinese martial art that emphasizes short combat strokes.

The characters 詠春 literally mean “Singing Spring” (as in springtime).

If you are wondering, the spelling and pronunciation of this martial arts style in English come from the Cantonese pronunciation of these characters. The second character sounds similar in both Mandarin and Cantonese, but the first is quite different.

Note: This title can be pronounced in Japanese, but only a Japanese practitioner of Wing Chun would recognize or understand this title. It is not considered a Japanese word or martial art at all.
