In China,there's an interesting birthday tradition for infants.A baby is one year old on the day he or she is born. One year later,friends and relatives get together for the baby's second birthday. They put several objects in front of the baby,such as some money,a doll, and a book. If the baby picks up the money,it means he or she is going to be wealthy. Reaching for the book means the baby is going to be a teacher, and picking up the doll means the baby is going to have a lot of children one day.
