The word "Happy Flying" comes from Zhuangzi, an ancient literary masterpiece, one of which is called Master of Health. One of the words is "music, the positive of yin and yang, is in harmony with its moral voice;" A gentleman takes Spring and Autumn as the literal meaning, and enjoys his virtue. "This sentence means that by balancing Yin and Yang, we can keep a happy mood and make people's virtue and beautiful voice coexist, so that we can really maintain physical and mental health.

On the other hand, from another article in Zhuangzi, The Emperor's Father, it is mentioned that "flying" means to make people reach a state of freedom and make the best performance in this state. This state does not need to rely on any outside help, but through their own efforts and cultivation. Therefore, happiness and flying also represent that a person can "fly" smoothly in the beautiful scenery of the world, thus reaching the peak of life.

With the passage of time, happiness and flying have gradually become spiritual beliefs and guides for people to enjoy life and pursue success. Generally speaking, happiness and flying represent a healthy, free, successful and beautiful attitude towards life. Only when a person is in a happy mood, constantly improves his self-cultivation and pursues the highest realm can he achieve "flying happily".
