The number of Chinese characters we commonly use is about 3,5, so there are a certain number of idioms and words formed by these words, and there are so many people in the country, which are obviously similar. I don't think there is anything unexpected. Especially for people who choose names, everyone chooses their favorite names according to some popular or current state in society. For example, as before, everyone would choose names related to national day patriotism and the party. Because everyone really loves the country, and it is also a developing state, so everyone will name these names.
Now, when we name our children after 8s, it's always the same name. Because people don't feel that they must have a masculine name or a neutral name like before. Life is relatively happy, and people's mentality is relatively peaceful, so in this happy state, people tend to be more flexible, happier, feminine, or a feeling of peace they want when naming names.
When choosing a name, it is decided according to the parents' artistic conception, parents' understanding and content. If parents are all well-educated people in their families, and they pay great attention to the implication and the development and feelings of their children in naming, then in this case, their names will be different. For example, women who are more feminine and gentle may name their children lightly, such as flowers or some plants. Of course, people who name their children according to their parents' preferences will feel good or feel good.
Some parents give their children great hopes when they name them, so they will give them names with such feelings as ambition, Peng and so on. Some names are more flexible, some are more neutral, and some are names with a lot of hope.
