What is patrilineal primogeniture, introduced during the Zhou Dynasty?

The Zhou Dynasty was a type of reign or governance in China. It lasted longer than any other dynasty in Chinese history.

It was characterized by the system of monarchy. The monarchs of the time practised agnatic/patrilineal primogeniture.

Patrilineal primogeniture is a system of passing down inheritance, whereby the main assets of a monarch or the head of a family are transferred to his first born son.

Younger siblings and female siblings were excluded from owning such property. The sons of the monarch come first on the inheritance train, before his brothers or other relatives.

All descendants through females or daughters (even though the descendants be male) stand no chance of gaining inheritance. The first son takes the chunk of the inheritance, while leftovers are shared by the other sons of the monarch.
