Chinese New Year
Houses are cleaned completely. In former times, sacrifices were made to the gods and dead family members in the days before the holiday. A "reunion dinner" happens in the evening of the last day of the traditional year ("New Year's Eve"). Older and married people give younger ones cash in red envelopes known as hongbao in Mandarin Chinese or laisee in Cantonese. China Central Television puts on a long show with many star actors, singers, and dancers. It is usually the most-watched TV show in the world each year. Lately, its ads have also become some of the world's most expensive, although they are still behind those during the US Super Bowl.
