Usually, we can set up a tombstone for the deceased ancestors according to the rest time of work. Tombstones are generally engraved with the name, place of origin, achievements, date of death, name of the person who built the monument and the relationship with the deceased.
If you pay more attention to Feng Shui when setting up a tombstone, you can consult Mr. Feng Shui and refer to the old almanac to choose the time to set up a tombstone.
Suggestion: Tombstones are generally erected around Tomb-Sweeping Day and Tomb-Sweeping Day is a national holiday; From the perspective of geomantic omen, this is also the best time to erect a tombstone for the deceased ancestors.
