Rong Yu and Reform

There are individual differences in how long people remember their childhood. Generally, the earliest memory may start around the age of two and a half. Researchers at Memorial University of Newfoundland in Canada collected and analyzed data from multiple studies between 1999 and 2020 and concluded that the earliest memories of childhood in research subjects are usually at least a year earlier than they thought, and can be traced back to the age of 2 and a half on average. Previous studies have believed that the starting point of most people's memories is three and a half years old. However, some people claim to remember moments before they were two years old or even one year old, such as "walking for the first time" and "wanting to tell mom that she was hungry before speaking". But generally speaking, many people lack continuous memory of experiences before the age of two or three, and are almost blank. Around the age of 7 may be a critical period when "childhood amnesia" begins to occur.

In ancient times, marriage was extremely particular. The "Three Letters and Six Etiquettes" were an important process of marriage, carrying people's expectations for a happy marriage. The "Three Letters" include the engagement letter when proposing, the gift letter recording the betrothal gift, and the greeting letter when marrying the bride; the "Six Rites" cover everything from the acceptance of the marriage proposal, to asking for the name, accepting the invitation, accepting the invitation, applying for the date, and then to the personal greeting. Although the details vary from place to place, they all follow the traditional marriage etiquette framework.
