It is good to hide Gan Xin in the Rizhu.
Zanggan Xin is the superior sun pillar among the sun pillars. He sits in the Zhengyin and is the official to rob the wealth. He is born with the Zhengyin. With the help of the robbery, the money changes from weak to strong, and the Zhengguan is balanced by Binghuo. Therefore, the Zangqian Xin is good in Rizhu. Solemnly declare, this answer is for reference only, please do not be blindly superstitious.
