What you are talking about is called auspicious selection, which is divided into many sects and the specific operations are also different.
Some of the good and bad fortunes you mentioned in the old imperial calendar are of reference value, while others are of no value or even harmful. Those instructions are just common folk customs, not real Feng Shui luck selection, because they were not compiled by real Feng Shui masters.
If what Lao Huangli said was correct, the knowledge of choosing auspiciousness would not need to exist and would have disappeared long ago. Its existence proves that there is a reason for its existence.
How important is the role of auspicious selection?
This is difficult to locate accurately.
For example, for cooking, when the oil is heated to what temperature is the most suitable for cutting the ingredients?
This is different for different dishes.
If you cook it too early, the aroma of the fried vegetables will not be strong enough, or the taste will not be ideal enough. If it is placed too late, some dishes may be fried, may have a slightly mushy taste, or other problems may occur. Therefore, loading the ingredients at the most appropriate time can ensure the most ideal dish.
For a professionally trained chef, as long as it is a dish he is familiar with, it is not a problem. However, this is just one link in the entire cooking process. Although it is also very important, it does not mean that it can determine everything. Only by ensuring that every aspect is mastered just right can you be a high-level chef.
If you are a novice without special training, as long as the basic cooking procedures are correct, the stir-fried vegetables will be edible, but the taste will be worse.
For Feng Shui masters, the same is true. Whether it is a Yang house (housing) or a Yin house (grave), every link will work during the specific operation. Only by ensuring that every link is Only when everything is perfect can we achieve the best results.
For some Feng Shui masters who are not real masters, as long as they get real inheritance (such as recipes) instead of hearsay, then as long as they follow the procedures, even if every link is not perfect, it is still It will be effective, just less effective.
But then again, even if you meet the best Feng Shui master, if your fate is not good and you have not accumulated enough Yin virtue, you will have no chance with the Feng Shui master.
If your life is good enough, and if you have accumulated enough virtues, then any time you choose may be the best choice. There is no need to check any auspicious book, it is fate. .
I hope my explanation will be helpful to you!
