Independent Writer

In my spare time, I take pleasure in observing the world , and writing about it in articles on my you can see in my Blog. I will write about the process and results of my own practice and reflections, or what I have see and hear in life and work. Some of the content is also the result of my sudden inspiration. I also write lyrics or translate foreign content into Chinese.

Moreover, you can follow my Channel where I share what I watch and create on the internet. Subscribing will keep you updated on my latest activities.

When offline, I enjoy reading and writing, immersing myself in my own "InfinitySpace".

About “而浮生若梦,为欢几何?”

This line originates from a Chinese poem by the Tang dynasty poet Li Bai, which I hold in great affection. It translates to the English sentiment as ‘Our floating life is like a dream; how often one can enjoy oneself?’ The poet intended to convey through this line that human life is ephemeral, akin to a fleeting illusion, urging us to embrace each day with a carefree attitude.
