The first day is for the welcoming of the deities of the heavens and earth, officially beginning at midnight. It is a traditional practice to light fireworks, burn bamboo sticks and firecrackers and to make as much of a din as possible to chase off the evil spirits as encapsulated by nian of which the term guo-nian was derived. Many people, especially Buddhists, abstain from meat consumption on the first day because it is believed that this will ensure longevity for them. Some consider lighting fires and using knives to be bad luck on New Year's Day, so all food to be consumed is cooked the days before. On this day, it is considered bad luck to use the broom.
Most importantly, the first day of Chinese New Year is a time to honor one's elders and families visit the oldest and most senior members of their extended families, usually their parents, grandparents and great-grandparents.
For Buddhists, the first day is also the birthday of Maitreya Bodhisattva (better known as the more familiar Budai Luohan), the Buddha-to-be. People also abstain from killing animals.
Some families may invite a lion dance troupe as a symbolic ritual to usher in the Chinese New Year as well as to evict bad spirits from the premises. Members of the family who are married also give red packets containing cash known as lai see or angpow, a form of blessings and to suppress the aging and challenges associated with the coming year, to junior members of the family, mostly children and teenagers. Business managers also give bonuses through red packets to employees for good luck, smooth-sailing, good health and wealth.
