In China, the United States and France, the 30th wedding anniversary is called the pearl wedding, and in the United Kingdom, it is called the ivory wedding. The meaning of pearl marriage is that after 30 years of running-in, marriage and feelings have been as round and precious as pearls, emitting a soft and moist white luster. The meaning of ivory marriage is that 30 years of marriage has eliminated the earlier fragility and innocence, and gradually developed a beautiful white brilliance, such as ivory.
