1. Height, Level, Alignment: Shop signs can only be set on the first floor, and they must be arranged in a flush-mounted plane layout against the wall. The top and bottom edges of each building's shop signs must be at the same height, and the signs must be level and aligned front-to-back.
2. No Window Obstruction: Shop signs must not obstruct windows. The height is generally controlled between 0.6 meters to 1.5 meters. Advertising and signs must not be placed on the walls between windows or below windows of buildings with residential functions. For non-residential buildings, when placing advertisements and signs on exterior walls, they must not block windows or the architectural facade details.
