What does Russian колыбельная mean in Chinese?

Russian is mainly used in Russia and other former Soviet Union member countries, and has been widely used as the first foreign language teaching in schools in Warsaw Treaty member countries. Among the countries it has joined, Russian is highly valued. Although many countries in the former Soviet Union have begun to emphasize the importance of local languages, Russian is still the most widely used language in these areas, and it is also the language used by these countries in communication. It is the only official language of Russia and one of the official languages of Kazakhstan, Belarus and Kyrgyzstan.

Extended data:

In Latvia, there are more than one third of the Russian population, mainly immigrants from Russia and the Soviet Union before the two world wars. The use of Russian in class is still controversial. In Estonia, Soviet-era immigrants and their descendants account for about a quarter of the country's current population.

The Russian-speaking population is less than one tenth of the total population of a country. However, about 80% of the population in the Baltic region can talk in basic Russian. In Finland, once a part of Russia, there are still several Russian-speaking communities.

In the 20th century, Russian was widely used in schools in Warsaw Pact countries, including Poland, Bulgaria, Czech Republic, Slovakia, Hungary, Romania and Albania. However, the younger generation is usually not fluent because Russian is no longer used in schools. In addition, influenced by the Soviet Union, some Asian countries, such as Laos, Vietnam, Cambodia and Mongolia, are still teaching Russian. Russian is still used as a lingua franca in several tribes in Afghanistan.
