Pure Brightness

The Pure Brightness, whose name refers to weather, falls on April 4 5 or 6. lt marks the start of clear skies, bright sunshine, bird songs, splendid flowers, and leafy green trees. In brief, it is when nature revivifies.

On the day of the Pure Brightness, people go to visit their family cemetery to mourn deceased family members. This is a time-honored custom. Plants sprout in spring. Spring rains increase the risks of tomb cave-ins, and the burrowing of certain animals may also damage graves. Hence the custom has been formed of coming to the ancestral burial ground on a specific day to clear weeds, add earth to the tomb mounds, and offer sacrifices to show respect.
