Have you ever visited a tea plantation? Acres upon acres of thriving tea shrubs high upon the mountain top, the leaves waving in the wind, bathed in sunlight. Meet the Yi Si (乙巳) aka the Wood Snake, the only Yi Wood Day Master to sit on the Fire element as the Main Qi. This flexible Yi Wood is a master in versatility.


At a glance, this is an unrooted Day Master without much support. It seems to be producing its Bing Fire (丙) Output Star, exerting strength to control its Wu Earth (戊) Wealth Star and defending against its Geng Metal (庚) Officer star.

It seems to be.

However, there is the relationship between the Bing Fire Hurting Officer and the Yi Wood Day Master is, in fact, a reverse production cycle. In other words, this Day Master is actually being produced by its own Output element.

Therefore, the influence of the Bing Fire (丙) will feature strongly in the Yi Si’s strengths and weaknesses.


Let’s examine the elements individually and discover the myriad strengths they bring to you, the Yi Siu Day Master:

  1. As mentioned earlier, the Bing Fire (丙) Hurting Officer Star plays a big role in how the Yi Si functions. This is where the creative energy and optimism of the Yi Si comes from. This element also brings you that ability to present fresh new perspectives on the same-old; same-old.
  2. Far from depleting the strength of the Yi Day Master, the Wu Earth (戊) Direct Wealth adds stability to this pillar. In addition to conveying determination to the Yi Si, it also represents the ability to maximize your resources and your knack for managing finance which in turn attracts many investment opportunities your way.
  3. Finally, the Geng Metal (庚) Direct Officer star injects a hefty dose of practicality and pragmatism to temper the idealism of the Bing Fire Hurting Officer.


Before we get into the weaknesses, I’d like to highlight a key point on how others are likely to perceive you, the Yi Si Day Master.

The most important thing you need to know is that you have the ability to project the outward persona of someone who is giving and selfless, yet at the same time, work towards your own goals and objectives.

Use this wisely, because a natural extension of this outward persona is that sometimes, you may give the impression of being secretive, a little aloof or perhaps even superior.


The presence of both the Hurting Officer and the Direct Officer within the same pillar may indicate a rebellious nature as well as the probability of a lack of self-discipline.

The Bing Fire (丙) Hurting Officer is great when its passions are channelled towards realizing your ambitions. But should the rebellious nature of this star take root, there is a danger that you may cast aside your well-laid plans in pursuit of pipe dreams and castles in the air.


Competitive by nature, accepting help does not come easy for the Yi Si.

Since you are unlikely to seek help, therefore, the only logical suggestion for the Yi Si is to consciously create self-mastery through discipline.

Remember the famous quote from Frank Jackson aka Frank Outlaw (particularly apt in this case):

“Watch your thoughts, they become words
Watch your words, they become actions
Watch your actions, they become habits
Watch your habits, they become character
Watch your character, it becomes your destiny”

As always, a final caveat. Without the ability to see the full chart, I must stress that the suggestions in this article are broad recommendations based on a single pillar.
