What happens when there is a ditch in front of the newly rented house? Please ask the master to take a look at it for me

When the house breaks water, it is either 100 or 0. There is a ditch in front of the main door, and the water will flow to the left when it reaches the door. There is also a small ditch on the left side of the house, which flows to the front one. You may have to measure it with a compass at the scene to know whether it is big or fierce.
