In the past, people's wishes to celebrate adults' birthdays were generally simple. Only some elders of big families, their children held a grand birthday ceremony to show their respect, without inviting relatives and friends, just a family reunion. However, in recent years, the ideological work practice of celebrating the birthday of workers and soldiers has gradually become popular in factories or troops. Usually put up a red list on your birthday, announce the name of the person who was born, and write a few words of congratulations. The leaders sent birthday wishes and birthday cakes, and some even added extra dishes to their comrades who celebrated their birthdays to show their congratulations and care. Between lovers, congratulating each other on their birthdays is usually regarded as a major event and can never be ignored. It can take the form of a congratulatory letter or a gift. This kind of gift is usually a souvenir with a symbol of love, but it doesn't have to cost a lot of money to enhance the feelings of both parties. For the adults in the family to celebrate their birthdays, there are usually some activities: the first choice is to eat birthday noodles. Eating noodles on birthday is a traditional folk custom in China, which means "longevity". In the south of China, it is a custom for the elderly to send birthday noodles to their neighbors on their birthdays. It's usually a bowl of noodles covered with pork chops. Neighbors should not be polite or refuse this. On the contrary, they should verbally express their birthday congratulations to their hosts. Secondly, prepare some rich dining tables, have dinner with the whole family on the birthday, and sometimes invite some close relatives and friends to get together. If the birthday party and the "birthday girl" live in two places, the family can still celebrate, but it is necessary to send a birthday congratulatory letter to the "birthday girl" in advance, and it is best for the "birthday girl" to receive it on the birthday. Thirdly, in recent years, many families are celebrating their birthdays and have increased the activities of eating birthday cakes. Cake is a homonym of "Gao", which means "Longevity". If there is no cream cake in the local area, you can buy ordinary egg cakes. Since ancient times, birthday ceremonies and customs have been divided into two sections. Early birthday etiquette is not as important as it seems. Only elderly people, their children often attach great importance to them, even if the birthday girls don't care, their children and grandchildren should make a fuss about this achievable etiquette.
