What does it mean to avoid a day on the moon? What are the taboos?

Death days refer to the days corresponding to each month in the China lunar calendar, which are considered as the death days of the deceased. According to relevant information, in these days, family and friends should avoid participating in celebrations, weddings and other festive activities, but should visit cemeteries and other mourning activities. There are still some taboos to pay attention to when the moon is closed, such as: it is not suitable to take planes, ships and other means of transportation, to avoid long-distance travel or gathering, and to break ground when opening a business. At the same time, it is not appropriate to do unlucky things such as sweeping graves, building graves and worshipping strangers. Abiding by these taboos helps to protect our own security and social harmony.
