Can you guard the gate without an escort room?

Can you guard the gate without an escort room? -The training room is not built at the gate, but the escort room is either built on both sides of the gate, or two escort rooms cannot be built symmetrically.

The core of traditional geomantic conception is axisymmetrical theory. That is, a straight line is extended from a certain point, that is, sitting on a mountain, along this straight line, spreading left and right, spreading back and forth, forming a symmetrical figure (symmetrical figure means: a figure is folded in half, and the shapes on both sides can completely overlap along this line), which is considered to be the most standardized Feng Shui scheme. In the natural state of the site, the terrain is complex, but the basic idea is to find the balance point of relative and symmetry and evaluate the concept of symmetry of the central axis. Such as: Zuo Qinglong, right white tiger; Vestibular case, leaning against the mountain; Tianxin uses ten things. All activities are based on the thinking concept of axis symmetry.
