Can I decorate it after the fifteenth day of the first month?

It can be decorated after the fifteenth day of the first month. At this time, the weather is getting warmer, which is also the peak season for house decoration. If it doesn't rain, you can start working at any time. But if the temperature in the north is below 5 degrees, don't paint or tile, because it will affect the construction.

Decoration time is usually in April and May, or in September, that is, in spring and autumn. Because there are many rainy days in summer and the air is very humid, if you decorate at this time, it will easily affect the construction effect, while the temperature in winter is very low and the paint is easily affected, so it is better to decorate in spring and autumn, but at the same time, you should also pay attention to the current temperature, especially when painting walls, which requires extremely high temperature.
