Can I fill the grave on July 15?

According to folk tradition, July 15 is a ghost festival, which is not suitable for grave repair. Because on this day, ghosts of the underworld will come to visit relatives of the dead, and repairing graves will disturb the dead and may have a bad influence.

However, if you really need to repair the grave, you can refer to the following suggestions:

1. Choose the auspicious day of the ecliptic to repair graves to avoid adverse effects.

2. Before the grave is built, worship should be conducted to inform the dead that the grave is about to be built, so as not to disturb the dead.

3. In the process of repairing the grave, respect the dead and try to avoid damaging the environment around the grave.

Generally speaking, if you really want to repair a grave, you'd better refer to the above suggestions to show respect and prudence.
