What's the difference between the traditional Chinese New Year custom and now?

In the past, every household would put up couplets, change the door gods, worship the kitchen god, celebrate the New Year (this form is many and complicated, not to mention it), visit neighbors' houses and get red envelopes, so here it is. Not much can be preserved now. Not much is used in cities, but a small part is used in rural areas. But travel everywhere. Setting off firecrackers and visiting some of them is purely a response. Some people even think that this is a kind of entertainment and a tiring activity.

The most important thing for the ancients to celebrate the New Year is to worship their ancestors. Whether in the countryside or in the city, the first thing on New Year's Eve and the first activity in the Spring Festival is to hold a grand ancestor worship ceremony. In addition to being held at home, people of the same clan will also be held in temples at home. After ancestor worship, it is the younger generation who pays New Year greetings to the elders. Other activities of the Spring Festival must be carried out after these two activities. This custom fully embodies the "gratitude" spirit of the ancients. They think that their happiness and joy today are given by their deceased ancestors and living elders, so at the beginning of this grand festival, they should invite their deceased ancestors back to play with their families and congratulate the living elders on their longevity. Now the Spring Festival is a day when people indulge themselves, communicate with "useful people", accept gifts and cash gifts, set off firecrackers to pollute the air, destroy the peace and threaten the safety of others, and waste resources to harm health.

The activities during the Spring Festival are still going on, and people's mouth corners are also rising, but its significance has failed. People here only know how to be happy, and children only know how to take red envelopes and play. Adults use this time to take their children to travel and visit, and use this time to "give gifts" to increase the friendship between people. Yes, there is nothing wrong with all this, but it has no special significance in this festival.
