2. It's neither bad nor bad: If it suddenly rains outside or the sun is very hot, sparrows fly into your house at this time, it's purely because they are avoiding "natural disasters" and have nothing to do with your feng shui fortune. However, in this case, you'd better not drive the sparrow out. Heaven has the virtue of good life. If borrowing land to shelter these creatures from the wind and rain is just a little effort, it will not only have a negative impact on you, but even increase your luck.
