Refuting Li Dingxin's Investigation of the Authenticity of Mao Zedong's Ancestral Tomb

Let's discuss the concept of "Rushou Long":

What is Rushou Long? Rushou Long, also known as Gelong, refers to the determination of which mountain orientation is being used. For example, if we position it at the Xushan Mountain, under Xushan there are Jiawu, Bingxu, Wuxu, Gengxu, and Renxu, collectively called the Five Sons Dragon. Since each dragon occupies five degrees on the circular compass, it is also referred to as the Seventy-Two Dragons of Chuanshan. In practice, one places the Luo Jing (compass) on the water ridge at the head section of the incoming pulse to see which character on the Luo Jing the central line of the incoming pulse passes through. If the central line of the incoming pulse passes through the Xushan Mountain on the Luo Jing, then one checks which group of the Five Sons Dragon under Xushan the work line falls into. For instance, if it passes through Bingxu, it is called positioning the Xushan Mountain with Bingxu Dragon, or Bingxu Earth Dragon Rushou, because the Naiyin of Bingxu is "roof-top earth." In practice, only Bingxu or Gengxu can be used under Xushan, and whether to use Bingxu or Gengxu depends on the length and advancement or retreat of the seasonal periods. Once the Rushou Long is determined, one can establish the basis for determining the direction and which dragon to use in penetrating the ground. Feng Shui is a chain reaction; without one link, there is no basis for proceeding to the next step. Li Dingxin claims on his website that he investigated Mao Zedong's ancestral tomb (2. Qi aspect: ① Water mouth located at the Yicheng Palace ② Rushou Long, Renxu Water Dragon ③ Chao Tang Water: left is Genchen Water, right is Dingwei Water). My question is, based on what did Li Dingxin determine that Mao Zedong's ancestral tomb is a Renxu Water Dragon? Does Li Dingxin know the exact year, month, and day when Mao Zedong's ancestral tomb was constructed and buried? If one knows the burial date, one can retroactively determine which dragon enters first. Without knowing this information, claiming that it is a Renxu Water Dragon entering first lacks any basis. Therefore, what Li Dingxin said is purely deceptive. One could also say that Li Dingxin doesn't understand Feng Shui at all and has been making a living by deceiving people all these years.
