How about fifteen?

Hebei area is divided into inside-out and bottom-up areas.

The most important thing in lighting on the fifteenth day of the first month is how to disperse the lights. Different lights have different meanings, and what lights are placed in what position. The twelve lotus lanterns should be placed under the niche of heaven and earth, and the twelve zodiac lanterns should also be placed in different positions. For example, dog lanterns should be placed at the gate so that they can look after the home. Chicken lanterns should be placed on the kang to eat scorpions and insects on the kang; Fish lanterns should be placed in front of the granary and the temple of the god of wealth, indicating that there is more than enough money and food every year; Putting lights on the steps of the building can illuminate the steps, and the whole roof should be placed in a square circle, which means that it can become a square only if there are rules; Five lights should be placed in the center of the yard in a circle, which means that the five grains are golden and the whole family is reunited.
