You can put a fish tank, and it is best to hang a curtain on the kitchen and bathroom door. If there is nothing to block the living room, the exhaust gas from the kitchen, the flame gas and the dirty gas from the bathroom will rush into the master bedroom and the assistant master bedroom, causing people living in it to be grumpy, often sick and weak.
If the bathroom is facing the dining table, the dirty air, odor and bacteria in the bathroom will directly pollute the food and affect the digestive system of people living in it.
