Flying Flight in Chinese / Japanese...

飛 is the single character for flight, flying, or to fly.

It can be a single character in Chinese and Korean Hanja. However, in Japanese, it's often understood as a female given name Fei or used to mean a rook (shoji). 飛 is best if your audience is Chinese.

飛揚 means flight, flying, or to rise upwards in Chinese and Japanese Kanji.

飛揚 is not the most common title for a wall scroll but if you have a personal reason or this idea is important to you, then go for it.

This can also be the personal name “Hiyou” in Japanese.

鵬程萬里 is an ancient Chinese proverb used in modern times to wish someone a long and successful career.

It's really about the 10,000 Flight of the Peng (Peng, also known as Roc is a mythical fish that can turn into a bird and take flight).

莊子
Zhuangzi or Chuang Tzu

Breaking down each character:
1. Peng or Roc (a kind of bird).
2. Journey (in this case, a flight).
3. 10,000 (Ten Thousand).
4. Li is a unit of distance often referred to as a “Chinese Mile,” though the real distance is about half a kilometer.

Direct Translation: “Peng's Journey [of] 10,000 Li.”
Literal meaning: “The 10,000-Li Flying Range Of The Roc.”
Perceived meaning: “To have a bright future” or “To go far.”

This proverb/idiom comes from the book of Zhuangzi or Chuang Tzu. It tells the tale of a huge fish that could turn into a gigantic bird. This bird was called a “peng” and was many miles long. This legendary size allowed the Peng to fly from the Northern Sea to the Southern Sea in a single bound.

Wishing someone “a Peng's Journey of 10,000 Li” will imply that they can travel far without stopping and will have great success, a long career, and a prosperous future.
