yes. Catering shops need to set up fire-fighting facilities and evacuation passages to ensure the safety of personnel. For the fire exits of catering shops, there are generally two kinds: main exits and secondary exits.

1. Main passage: refers to the shortest path from all indoor locations to the safety exit, and is usually the main passage for personnel evacuation. In catering shops, the main passage is generally the corridor, hall and other places in the store, which should be kept unimpeded to avoid stacking or blocking of goods.

2. Secondary channel: refers to other channels connecting rooms, or channels connecting different rooms. In catering shops, secondary passages usually refer to aisles, corridors and other places in the store, which are used to assist personnel evacuation, but their functions are not as important as the main passages.
