Is the upstairs bathroom and downstairs kitchen auspicious? why

If the functional area upstairs is used as a toilet, then the people living downstairs must not be used as a kitchen, because the toilet is a place to discharge waste and garbage, and the kitchen is a place to cook for the whole family, which is a clean and hygienic place. If there is a toilet upstairs and a kitchen downstairs, the physical condition of the whole family will get worse as time goes by, so you'd better know about it before making a decision, otherwise it will be too late to regret it when the family is well.
