The building faces south, with open courtyards and roads in front, a wall behind it and a river outside it. Is this feng shui good?

Very good, very good!

1, "sitting north facing south", the best choice. 2. "There are open courtyards and roads ahead", which is estimated to be very flat and rich. 3. "There is a wall behind the building", for protection, for defenders and peace. 4. "There is a river outside the wall". For protection, for endless flow. Peugeot is very lucky.
