My room now is full of windows, and the air convection between doors and windows. I have a group of so-called "Feng Shui friends" who come to my house to play. Some people make irresponsible remarks, but I just laugh it off. It's very hot now and the windows are open, so I seldom need to turn on the electric fan. In winter, it is very comfortable to close the window tightly. I went to their house, and when it was hot, oil came out. I don't want to believe that Feng Shui has suffered like that. I just don't accumulate wealth now, and I will be changed by future generations after my death. I don't want to believe in "the road to accumulating wealth by suffering" anymore. Speaking of refund, I have parents who are almost ninety years old. It's normal to spend money, but they can take care of themselves, unlike asking me for a refund. I have been to some places and learned some things. Now the people there are extinct. I have considered many things with the concept of Feng Shui, and the conclusion is not like the argument in the Feng Shui book. At present, domestic feng shui masters can be regarded as real feng shui masters if they can adjust their feng shui to the point where people will never become extinct. Otherwise, many arguments of Feng Shui need further study and demonstration.
