KC posts the same question to Howard as it was not answered or it has not been properly answered or not to the point.

Howard,

My question is not about 3 Eras and 9 Periods 三元九運 and 2 Eras and 8 Periods 二元八運. I am particularly interested in 玄空六法 xuan Kong Liu fa. I think you should have read about Lin Zhi-Rong 林志榮 's book玄空六法秘訣圖解. I am not talking about 紫白元運 nor about 紫白飛星.

As you have an article written about xuan kong liu fa 玄空六法, therefore, I think you should know about xuan kong liu fa 玄空六法. I saw the example you posted in your blog talked about Master Tan Yuan-Wu's 談養吾 ‘s theory and application of Xuan Kong Liu Fa 玄空六法.

I wanted to know your opinion about what Lin Zhi-Rong 林志榮 said in his book玄空六法秘訣圖解. Lin mentioned that YuanYunFaWei元運發微 talked about 挨星山運水運，元運發微 said 水運starts from 2002 and Master Tan Yuan-Wu's 談養吾 Xuan Kong Liu Fa 玄空六法 said水運starts from 1997, in your opinion, which theory is applicable and correct?

Regards，

KC
