First, take pictures in front of the grave.
In Feng Shui, there are two kinds of houses: Yang House and Yin House. Both pay attention to "hiding the wind and gathering the gas." The purpose is to make all kinds of qi harmless and gather the beneficial breath of the living and the dead at the same time. Therefore, Yang houses gather in Yang, and cemeteries generally choose places where Yin qi gathers.
Some people think spring is beautiful and like some photos. Some people also "take photos" with their ancestors in front of the cemetery to commemorate them. Yin Qi gathered in the cemetery is likely to interfere with the aura of people in the photos, affecting health and fortune. Especially those who are weak or unlucky, we must be alert to this.

Second, set off firecrackers.
When many people go to the grave, they like to set off a string of firecrackers in front of the grave after the ceremony of burning incense, offering wine and offering sacrifices to create a festive atmosphere for their ancestors. The cemetery is where Yin Qi gathers. The more vigorous Yin Qi is, the more sensitive the ancestors are to their offspring, that is to say, the more they will show the effect of shading.
Firecrackers are violent and pure things, which were originally used to exorcise evil spirits. When setting off firecrackers, it will release a lot of positive breath, which is likely to interfere with the gas field of the cemetery. The sound of those explosions may also disturb the soul rest of the dead.

Third, cause yellow fire.
Many places still keep the custom of burning paper money, and the fire source is not handled properly after burning. After people leave, the wind blows on Mars, causing the nearby vegetation to burn, which often leads to "a single spark can start a prairie fire". Abandoning wild fires is harmful to forests and public safety, but from the perspective of geomantic omen, it is very unfavorable to the dead and the living.
The smell of a place is mostly judged by the growth of vegetation. After the yellow fire, the vicinity of the fire source, including the cemetery, must have been burnt, which is harmful to Feng Shui first. Furthermore, after Tomb-Sweeping Day, all kinds of animals have already ended their dormancy and climbed to the surface. After the yellow fire, these animals are hard to escape from the fire.
