The first is to look comfortable. If you set the position of the porch, it will make people feel uncomfortable at first sight. No matter how good the feng shui in that area is, it is not suitable. Comfort is the most important thing at home. Therefore, regarding the entrance, the location should be comfortable.
The second is to be consistent with the decoration style of your house. I don't want the home decoration to be western-style. The whole pattern is out of place because the porch is really Chinese.
The last one is that the entrance should be wide enough, because there should be room for guests to change shoes, buffer their mood and put things. If it is too small, it doesn't make any sense.
