Birthday celebrations in China are reserved for only certain milestones, generally — a person's 1st, 10th, 60th and 70th. A child's first birthday is thought to be quite important, as what happens on that day is thought to influence his or her entire future. The parents will place the baby in the center of symbolic objects such as coins, books and dolls, and whichever item a child reaches for first is considered an indication of his or her path in life. (If they pick a coin, it is thought they'll be wealthy; a book means they will be learned; a doll might mean a big family.)
For the party itself, friends and relatives are invited for lunch, and extra-long noodles are served to wish the birthday child a long life.
