In what countries is Tai Shan practiced?

"Tai Shan" is a mountain in China, not a practice. Are you perhaps thinking of a different term?

If you're looking for information about practices or religions, please clarify your question. For example, you could ask:

* "What countries practice Tai Chi?"

* "What countries are Taoism practiced?"

* "What countries practice meditation?"
