"Doing white things" means doing funerals or mourning ceremonies. In China's traditional culture, since ancient times, people have attached great importance to offering sacrifices and mourning to their ancestors, believing that this is a filial piety and a manifestation of respect for their elders. When an elder in the family dies, later generations will deal with the "white matter", announce the funeral, organize the funeral, and cover the lights in the process to express their respect and condolences to the deceased. Therefore, it is a traditional custom to respect ancestors and express grief.

In modern society, with the progress of society and the increase of cultural diversity, different regions, different nationalities and different religions have their own funeral etiquette and customs, but the tradition of "doing white things and covering the lights" still exists and many people still attach great importance to it. In addition to expressing nostalgia and respect for relatives, it is also a way for family members and relatives to gradually accept loss, accept reality and relieve mental illness. Therefore, it is not only the continuation of traditional culture, but also the spiritual comfort of bereavement in dealing with white affairs.

With the change of lifestyle and the increasing frequency of cultural exchanges, the current funeral methods are increasingly diversified. However, as a traditional custom, "doing white things and building lanterns" has spread to this day. In some areas of China, such as the south and southwest, the characteristics of this custom are more deeply rooted in people's hearts, and also reflect the local cultural traditions and religious beliefs to some extent. In addition, it also reminds us that while respecting traditional culture, we should actively advocate an open, inclusive, rational and scientific funeral culture to ensure that it conforms to the legal system, ethics and moral norms of modern society.
