When Hakkas build new houses, they usually choose dates related to the ninth festival, such as the ninth and eighteenth day of the first lunar month. The number of floors and rooms in the completed building is also a multiple of 9, which means that we can live together for a long time. "Nine" is particularly important in the wedding ceremony of Hakkas. When men and women meet and exchange invitations, they usually choose dates related to Nine. The mantissa of the engagement fee should be "nine", such as 1.999 yuan. The wedding team should also make up nine people, and all gifts should be nine parties for good luck. For Hakkas' birthdays, they have to make 865, 438+0 or 360 birthday pins, and all the dishes they use are "three, six and nine", such as three fresh soup, stewed dog meat (nine dogs), leek tofu, Chongyang (99) birthday cake and so on.
Because nine and leeks are homophonic, children should eat leeks when they drop out of school. Hakka folk songs also use nine-letter leeks, such as: "Swallows cross Jiujiang with mud, my sister sends Lang out of the country, and nine kinds of leeks are planted in September. The two have a long history. " Hakkas attach importance to Nine, which is also reflected in the fact that they regard the ninth day of the first month as an auspicious day. After the Spring Festival, people who go out to work or do business will not leave home until the ninth day of the ninth lunar month, expecting good luck and prosperity in the new year.
