What do you mean by Lunar New Year population?

On a certain day in the lunar calendar, a new population enters a family or social group and becomes a member of it.

Entering the crowd is an important moment for a family or social group, which means that new life or members join and bring new hopes and expectations. In the traditional culture of China, people also have certain rituals and customs when entering the country, such as setting off firecrackers and pasting red paper to express congratulations and blessings.
