Yes, we do.
On the twenty-seventh day of the La Month, there is a custom of washing clothes.
In our lunar calendar, on the twenty-seventh day of the La Month, there is a tradition of washing clothes to remove bad luck and slaughtering chickens and going to the big market.
In traditional folk customs, people concentrate on bathing and washing clothes on the twenty-seventh and twenty-eighth days of the La Month. According to legend, bathing on this day can remove the bad luck of the whole year and wash away the diseases of the past year. Therefore, regardless of wealth, everyone prepares for the coming new year by bathing and changing clothes, which has led to the proverb "On the twenty-seventh day, wash away the illness; on the twenty-eighth day, wash away the dirt."
Therefore, it is necessary to wash clothes during the La Month.

As for the thorough cleaning during the La Month, I suppose everyone is familiar with it.
However, not everyone knows why we need to do a thorough cleaning during the La Month.
There was a custom of sweeping during the La Month in the era of Yao and Shun. Because "dust" (尘) sounds like "old" (陈), sweeping dust during the La Month has the meaning of "removing the old and welcoming the new." From the perspective of feng shui, this will sweep away all the negative energies such as "poor luck" and "bad luck" from the house. Sweeping during the La Month can be hoped that the fortune in the coming year will become better and better.
