Rayall,
Based on your description, I strongly suspect that she was born in Ding Si hour, not Wu Wu hour. The software that you use does not account for time adjustment.
You did not provide the birth city. But based on my guess, she was born in Peninsular Malaysia or Singapore, and thus the solar time of birth is around 10:30, anyway before 11 am. Could you confirm this?
If correct, then this would translate to the Ding Si or Snake hour.
She doesn't act her age, acting more like a teenager and throws a lot of tantrums. She doesn't listen to people even when they mean well and it's difficult explaining things to her.
It's due to my concerns with this behaviour that I'm asking for advice.
With the Si (Snake) hour, the above traits can be explained by the
Si-Yin harm interaction. Yin Tiger is Officer (Authority), so the harm interactions means she "rejects" authority, and can be seen as acting like a teenager.
