Chinese Wedding Tea ceremony
 

Lotus seeds and two red dates are used in the tea for two reasons. First, the words “lotus” and “year,” “seed” and “child,” and “date” and “early,” are homophones, i.e. they have the same sound but different meanings in Chinese. Secondly, the ancient Chinese believed that putting these items in the tea would help the newlyweds produce children early in their marriage and every year, which would ensure many grandchildren for their parents. Also, the sweetness of the special tea is a wish for sweet relations between the bride and her new family.
