Might as well since it is tomorrow. Might vary across Chinese diaspora or mainlanders.
Anyway every time when the lunar calendar restarts. Chinese celebrate Chinese New Year. It begins on the eve whereby everyone has to come home to eat Reunion Dinner usually with their extended family. If you are married it would be the husband's extended family. Although sometimes they would have a similar dinner before that with the wife's extended family.
The next day would be visiting relatives and wishing them happy new year with mandarin oranges, usually with a blessing in advancement in wealth, health or family. In return red packets are usually given in return. They are packets containing money. It is taboo to open in front of the person and no, turning around to open it still counts.
The amount of money inside is actually a interesting social game. Too much and you are seen are flexing too hard and spoiling market, so little and people will think you are cheapstake. You also give in relative relationship to the person. A grandparent is going to give their grandchildren far more than a family's child. Hence Red packets are quite personalized to the receiver.
The period of celebration 2 weeks. Over here expect pestering relatives, steamboat dinners, a lot of indoor gambling and the police closing one eye on it. A local SEA tradition is Yusheng (3rd pic related), where a collection of vegetables and meat is placed together with sauces and crackers. After some wishes and blessings, the people toss the food into a messy mixture using chopsticks making loud declarations of what they want to happen. The higher you throw, the more likely it is to happen.
