On the morning of New Year's Day, I usually stay at my parents' house for one day and leave at night. Even if you can't stay until evening, you should have a big lunch. This lunch usually has chicken and fish. Even in times of material scarcity, this lunch must have six courses.
For the new son-in-law, the significance of the second day of the Lunar New Year is even more unusual. On this day, the new son-in-law will express "thanks" to her parents-in-law and marry her daughter to herself. On the second day of the second year, the married daughter will go back to her mother's house, and her husband will also go with her, so it is commonly known as the husband's day. Take a present when you go home. This is called holding hands or accompanying hands. On this day, the daughter who goes back to her parents' home must bring some gifts and red envelopes to her children and have lunch at her parents' home.
On the second and third day of the first month, the married daughters go back to their parents' homes to celebrate the New Year with their husbands and children. When a daughter returns to her mother's house, there must be a big bag of biscuits and sweets distributed by her mother to her neighbors, just like the scene of the New Year.
