為學日益
In the pursuit of learning, knowledge is increased daily.
為道日損
In the pursuit of Tao, actions are reduced daily.

As a Taoist Priest, SOP compliance.
As an Average Layman, I live my life Naturally with simple Tao philosophy. Belief is not a fact. God knows if I could have better next life, happily ever after, ....

Experience my grounded life with full of possibilities. Smoothen the fluctuation response towards Body-Mind-Emotion-Energy.

I smiled when people condemned me not knowing how to conduct ritual but they paid to invite me. Many people envying me that so many spiritual beings so call deities wanted to connect with me but my SOP is Hi-Bye with respect. Organize my priorities and pursue while I’m alive 🤓

My dad was a student of the 63rd Celestial Master Zhang EnPu 張恩溥 before I was born. Familiar with Regional Taoist Priest leaders in Singapore, Malaysia, Vietnam, Hong Kong.

Not familiar. Only know how to read the sound sequence since very young. Occasionally when I discovered a Natural Geopathic Stress Line in Client’s house, I may use Compass to verify the stress propagation by Geo-Direction.
