According to the people I have come into contact with during my years of study and work, I personally prefer to go to Beiwai!
It can be said that at present, the main forces of all high-end, atmospheric and high-end units related to Russian at home and abroad that you can imagine are basically northerners! Students of Beijing Foreign Studies University have a solid basic knowledge of Russian and strong practical ability, and can adapt to the needs of Russian in different fields and majors in a short time! I am also an undergraduate majoring in Russian. After studying in college, I still feel very admired by those people who are studying abroad. Moreover, if you know more, you will find that there are a large number of talents from North China in the Ministry of Foreign Exchange, the Ministry of Commerce, the Safety Supervision Bureau, embassies and consulates abroad, and foreign companies or overseas offices of top 500 central enterprises. They are quite famous in Russian circles, and many of their predecessors are already high-level or leaders!
With its profound Russian teaching strength and location advantages, Black University has also won the favor of many Russian people. Several of my classmates went to Black University for postgraduate entrance examination. However, there are not many people in the Russian circle in Beijing at present, so I don't know much about what fields Russian graduates of Heilongjiang University are engaged in.
Of course, there are many universities in China with excellent Russian, such as Peking University, Beijing Normal University and National People's Congress.
The above are only personal opinions for reference!
