In the past, it was important to have high thresholds to prevent money from flowing out. Therefore, when we visited the courtyards of rich people’s homes, the thresholds were very high.
But that doesn’t matter now. Because rich people buy cars, in rural areas, the main entrance is often used as a garage, and even the threshold is omitted. This is a social trend. For example, big cities all pay attention to barrier-free roads to facilitate the passage of disabled people. This is the progress of the times and the progress of civilization.
