We often heard of this ‘Mystical‘ Feng Shui model (and often clueless about it) where the dragon side must be stronger than tiger side, a solid and broad mountain as backing so that we are blessed with nobleman’s help (贵人星) and an appealing bright hall (明堂) – symbolizing prosperity and smooth journey ahead.
How do we then measure and assess all that? In this article, I share how I’ve use HeTu (河图) numbers as a yardstick to this demystified this ‘Mystical’ model.


When I apply HeTu (河图) onto this model, the number are divided into 3 layers: 生数,成数,核心 (人).
1, 2, 3 & 4 are known as producing numbers (生数) and they form the inner arrangement called ‘body’ – 体.
6, 7, 8 & 9 are known as forming numbers (成数) and they form the outer arrangement called ‘application’ – 用.
5 resides in the kernel and is the separation distance between producing and forming → e.g. 1 (producing, 生数) + 5 (kernel, 核心) = 6 (forming, 成数).
As such, this draws the distinction between inner and outer arrangement, which gives rise to an important concept where the inner (阴) and outer (阳) arrangements are to be use complementarity (生成合用). This is also known as the layer of 人.


Knowing these numbers aren’t sufficient, as each number is sub-defined into Yin and Yang.
Yin (阴) possesses the properties: Still (静), absorb/receptive (吸收) has a form(有形), internal(内), self (我) and therefore perceived as a ‘body’ (阴体).
Yang (阳) possesses the properties: Movement(動), disperse/radiating (散/發射), formless(無形), external(外), others (他) and therefore perceived as a ‘force field’ known as ‘Qi’ (阳气).
Overlay the Dragon, Tiger, Tortoise, Phoenix over HeTu (河图). This the reason why internally Dragon (Left Side) is Yin (阴) / Quiet (静) therefore favours the external to be Yang (阳) / Movement (动). And on the Tiger (Right Side) is Yang (阳), prefer externalities to be Yin (阴) / Quiet (静).
Yin (阴) is receptive and exhibits an accumulative image. This means habit and specialization are Yin (阴).
Yang (阳) has a ‘kinetic’ nature therefore promotes the ability to innovate and visualize. This means thinking capability and intellectual is Yang (阳).
In summary, could be categorized into 4 broad aspect:
Dragon → Rank, Male, Intellectual, Contemplation, Strategy
Tiger → Career, Female, Habits
Tortoise → Nobility, Elders, Nobleman, Supports, Thinking
Phoenix → Specialization, Friends, Kids, Wealth
