Please look at the auspicious answer: the question of erecting a monument to the deceased parents.

1, the time of erecting the monument is not very important, because it has been buried. In fact, there is no need to erect a monument, and there is no need to erect a monument. Good feng shui is still good, bad feng shui is still bad. And even if it is necessary to build a monument according to the sitting direction and the specific feng shui environment, the specific time can be chosen.

2. Monuments generally stand on the feet, but some areas stand on the head, which still does not affect the real feng shui effect in practice. So you can decide for yourself.

There is nothing particular about tribute, as long as it is not for garbage. In addition, it is suggested that you can burn some gold and silver ingots made of gold and silver paper or gold and silver bricks when you go to the grave. That's what the underworld is like (a little superstitious, but for the sake of parents, it's better to burn it)
