In our legends, the Jade Emperor, the ruler of the heaven, descend to earth to inspect the world on this day, to see if every household lives an honest, frugal, and diligent life. As traditional value leads, people who work hard but live poorly should be sympathized and rewarded. To show the frugality and pray for the emperor's reward, traditionally people make bean curd, or Tofu, cheap food in China.
In northeast China, people make a decent amount of Nian Dou Bao, a kind of bun made of glutinous millet stuffed with red bean paste. Nian Dou Bao is also a staple food during the Spring Festival.
Do the laundry, bathe or take a good shower. Those activities symbolize for washing off all the bad luck and potential illness in the upcoming Chinese New Year.
In places like Beijing and Tianjin, an old tradition is to eat a rooster. Most people prefer a rooster instead of hen because of its majestic looking, and believe it will bring good luck.
It's a tradition to prepare in advance all staple food for the whole family to eat during the first week of Zheng Yue (the first month of the Lunar New Year). Usually, the staple food is flour-made because it's easy to store. The activity starts from 28th and may last for one or two days.
People from the north make steamed buns with leavened doughs, while people in the south prefer Year Cake, or Nian Gao, made by glutinous rice. The steamed buns can be in various shapes, including cute animals, flowers, etc.
People in most of the areas get up early to sweep tombs for their ancestors and burn incense and joss papers in memorial of them. This is also a reflection of the traditional value "Xiao," or filial piety, in China.
Finally, it's the Spring Festival Eve. This day is regarded as the most important day for family reunion throughout the year. Children who work or study outside the hometown, return home to celebrate the festival with their family.
The whole family enjoys a big feast at night while watching the Spring Festival gala. They stay up late and wait to ring in the New Year. A must-eat food is dumplings. Elders give kids red packets, or red envelopes, with cash in them.
In the days between 28th and 30th of La Yue, people also put on couplets on the gates, paper-cutting decorations on the windows, and New Year pictures on the walls of their homes to express their best wishes.
Embracing the first day of the New Year, people visit friends and relatives' homes and make New Year's greetings to each other. They use auspicious words to pray for good luck in the New Year.
Gong Xi Fa Cai (congrats for being more prosperous and better off), Wan Shi Ru Yi (everything goes as you wish), Shen Ti Jian Kang (being fit and healthy) are among the most frequently used greeting terms.
This day is called "Zheng Yue Shi Wu," or the Lantern Festival. Except for another warm family reunion, every household also hangs lanterns in front of the gate or on the balcony. It's also common to use colored lights to decorate the windows.
In some specially-held local lantern fair, there are riddles written on paper hanging under the lanterns. People can entertain themselves by guessing the answer of the riddles. A typical food on that day for northerners is Yuan Xiao, a ball-shaped dessert made with glutinous rice. Southerners eat Tang Yuan, a similar meal made by different techniques.
