Why are Russian names so long?

Russian names consist of first name+father name+surname. The name part is your own name. The father's title is a variant of the father's name to show whose son this is. Surnames, like our surnames, are handed down from generation to generation and cannot be changed (because surnames are also divided into yin and yang, that is, men and women, so the word forms are not exactly the same, and women can change their husbands' surnames after marriage). Take the familiar Russian name Putin for example. His full name is владимивладировв. This change has a special set of rules. Men and women are different. If it is a daughter, the change of the father's name is владимиовнапут. Usually, when we call Russians, we can call them by their first names or nicknames if we are peers or juniors. If you are an elder, for example, you should call your teacher by his first name+his father's name (this is very strict, and it is impolite not to add his father's name). First name+father name+surname is only used in very formal occasions, but if you address the president, prime minister or writer or celebrity, you will address your surname to show respect, such as President Putin and Prime Minister Medvedev. Russian should correspond to ский and нова, namely Skye and Nova, which are suffixes of surnames. To give two examples, such as Tchaikovsky and ivanova, Tchaikovsky's full name is пётрил?ичайковск. Russians also feel that they are.
