Pls tell me more about the Chinese scientist?

I do visualisation techniques. Mostly, I’m on a soft picnic blanket on a hill with long grass blowing gently with a mild breeze on a warm day. I can smell nearby flowers and I can hear a nearby brook bubbling over little rocks. I focus on the sounds, smells and visuals, and overall sense of peacefulness till my brain drowns out whatever is stressing me out and keeping me awake.
