What floor is good for a couple and two 85-year-old cows to buy a house?

I think it's best to choose the floor according to your actual requirements, mainly depending on what factors you value. If you just want to consider choosing a floor when you are husband and wife, I can give you this suggestion: there is a word with a good meaning, which means "running [bēn]". It's popular now, which means it's awesome! You and your wife are both cows and want to hold hands for life. Formally, it can be understood as "shrinking", which means that two cows hold hands and know each other. You are sure to have children, two children in a cow's life, that is, a calf (cow or not). The calf stands on your shoulder, which can be formally understood as [bēn]. You and your wife have two cows standing hand in hand on the ground-the first floor is down-to-earth, your child is standing on your shoulder, and the second floor is the higher end than you, which means going up a storey, so if you want to be superstitious in this respect, you can choose the house on the second floor.
