The balcony of the house I bought faces south, and you can see a river that only flows to the right. Is this feng shui good?

That's good. Because there are mountains and waters facing south, you have chosen a good environment. The house belongs to Jinjiao, and there are mountains and waters around it. The overall flow direction is better. In fact, the house still needs to be decorated by itself, which is an external cause, so don't care too much. As a house facing south, it's good, and this one you chose is also good. The rest is that you should take care of this small home and make your home a little warmer. Then life will flourish and the family will be healthy and safe.
