1. Kitchen and house. As can be seen from the idiom "A clever woman can't cook without rice", a clever woman refers to a chef and a clever woman refers to a kitchen.

2. In ancient times, poor families only cooked in the hall without a special kitchen, so they only called the stove "in front of the hall", the kitchen of rich families was called "kitchen king" and in the military camp it was called "kitchen".

In ancient times, people often set the kitchen for eating in the east of the main hall, so it was also called "East Kitchen". Cao Zhi, a gifted scholar in the Three Kingdoms period, said in the poem "On Disaster": "The days are short, and there is more than enough fun. It is to set up a jade bottle to run an eastern kitchen." Not only was his residence arranged like this when he was alive, but so was his grave after his death. Even the kitchen plan in the ancestral hall where the dead are sacrificed is located on the east wall.
