Chinese Luna New Year, a.k.a, the Spring Festival

the first day of the Chinese Lunar New Year

to wish somebody a happy Chinese Lunar New Year

a traditional ritual before new year's eve; to post the red couplet on the door.

a traditional ritual between the elders and the young of the new year; to give the young a red envelope packed with money inside when they '拜年' to you.

a tradition and already a history of the new year; to set off firecrackers.
p.s. Because of the air pollution control in most cities, we do not do it in the urban area anymore.

Spring Festival Evening Gala.
p.s. It is a tradition for every Chinese family to gather and watch the show on CCTV 1 on new year's eve, at least my tradition. We enjoy criticizing it.
