It is a geomantic saying that ancestral graves emit blue smoke. Blue smoke is a kind of blue gas, an auspicious gas and a good omen. According to the past, you can be an official. Now many people don't have ancestral graves, so they are not allowed. Another solution is that when you make a fire, blue smoke will come out, indicating that you will "fire".
Although the original intention of smoking in ancestral graves is to do good deeds and be a high official, there is irony and swearing in China's profound culture. For example, if someone is promoted to a small minister and others are dissatisfied with irony, they will say that the other party is a ancestral grave. It should be noted that flammable items such as firewood and hay cannot be placed on the grave. The older the grave, the more likely it is to produce combustible gas. When worshipping and burning paper, the high temperature of burning paper money may make the grave burn carelessly, causing a lot of trouble.
