What is the big dipper robbery in mysterious geomantic omen?

The big dipper robbed:

Beidou goes to rob, leaving the palace should be consistent, and the parents are all Samsung combinations. In a real robbery, the stars in the third house of earthquake, drought and separation must be in the combination form of 147, 258 and 369. And not every Yuan Yun can do it! Can only say so much, no matter how much, I won't understand. A Feng Shui master can't do more than 10 in his life!
