Liu Yao has the Six Animals, and one of them is
Tortoise. What better tool to analyze the health of a
turtle than Liu Yao?

About setting. Yong shen Offspring as mascot. Self and Other I am not sure, but I thought before casting that self is turtle and Other could be environment.
Also, we are talking about the
tank, which is what gives protection for the turtle, so it's the
Resource line. And about disease too, which is represented by the
Officer line.
Scenario B:
1. Officer line goes to Wei Tomb
2. Si Resource goes out of hiding mode
3. Therefore, Si combines with Shen, which is Offspring (turtle)
4. This combination cannot overcome Shen, because Shen is strong by both Month and Day. This is a beneficial combination for Offspring
This shows that scenario B is quite good.
Now, the Others line represents the environment, which is Asset. Asset represents food, and goes into the Day Tomb. This suggests that food need to be improved for the turtle's health. This is not the main question, but still related to the turtle's health.
I have analyzed Scenario A, too, but to save some time, the conclusion is that
Scenario B is better than A.
