1. The weak body in the eight-character refers to the fact that your horoscope is dry, and you can't get the support of the monthly order, or even be suppressed by the monthly order, and there is no corresponding seal to support it. That is to say, there is no India to give birth to him. And less than the shoulder, there is no same five elements to help or less help. And there are no roots in the earthly branches.
2. Take an example. For example, Jiamu was born in the unitary month, and there is only one Jiamu in the sky, and no one is drowning. There is no sea water or yin wood in the branch. Then it can be said that this Japanese Lord is weak. This weakness means that the five elements of the sun column are not strong and rely less.
