I would like to ask the Feng Shui master, how does the road separate the water from coming and going? At the crossroads, the main road is big and the lanes are small. The main road goes straight and the lanes are horizontal. The store is on the cross lane at the intersection...

No matter how flat the road is, it still has its ups and downs, right? The lower end is to get to the water. If you really can't see it, go to the center of the city for incoming water and the one outside the city for outgoing water. When choosing a store, you should face the flow of traffic and people for coming, and carry those behind for going. When water comes in, Qi is gathered immediately, and when water is removed, Qi is dispersed. Gathering Qi leads to prosperity, dispersing Qi leads to decay.
