To have or do the ceremony to start the rice harvest.
When the rice is ready to be harvested a person, who is expert at such things, goes to the field on the same day of the week as the rice was planted in the beginning of the season. He ties seven stalks of rice together and smokes it with incense. Then he cuts some stalks surrounding the tied ones and places this cut bundle on the ground near the tied stalks. It remains there until the harvest is finished.
When the rice is ripe an expert goes and performs the ceremony to begin the harvest.
