The entrance door of my house is facing the door of the master bedroom, but there is a long corridor in the middle, so is Feng Shui good?

Generally speaking, it is taboo for the entrance door to face the bathroom door. For the master bedroom door, it doesn't matter much. If you are particularly concerned about Feng Shui, just make a screen. You should carefully check whether the entrance door and bedroom door are just right. If not, it doesn't matter.
