Represents hair. A wedding gift of 4,000 yuan represents hair, which means a good wish for the couple to get along well in everything, for a hundred years and for life. At weddings, more people like to set the number of wedding gifts at 3,000 to 4,000 yuan. This is because this number is pronounced "Shengshengfa" in Chinese, which represents the beautiful wish of harmony and eternal life for a hundred years.
