I have the opportunity to be a staff member of the Ministry of Foreign Affairs, an excellent Russian translator who accompanied the head of state on a visit, and a literary and art worker who performed in the Russian/Chinese Year of the two countries. Also, as a staff member of Russian TV station, Putin regularly communicates with netizens online.
If you want to talk to him, it's a bit difficult. Either you become a foreign minister or a president/prime minister, or you become a media person like Shui Junyi and conduct "high-end visits" every day, or you become a celebrity and hold a grand charity dinner in Russia, and Putin may be invited, or you become a Russian citizen and a local citizen. And Putin is now the prime minister. He will manage domestic affairs and come to see you when he is free.
However, when you came out, I didn't know whether Putin was still in office. Maybe he was already in back in the game. You may be an ordinary tourist, you can visit him!
