Japanese is the largest minority language major in colleges and universities, second only to English. As you know, the Japanese economy and Sino-Japanese relations are not very optimistic. Japanese means "go in and laugh, come out and cry." It's simple at first, but it's difficult to go deep.
Russian, as long as the institutions are concentrated in the northeast and northwest, Heilongjiang University, Beijing Foreign Studies University and Shanghai Foreign Studies University, only three universities have Russian colleges. Prospects, the northeast, northwest and east coast seem ok. Russian and Japanese are the opposite. "Go in and cry, laugh out" is difficult to get started, but it's very simple after mastering the rules.
German, science and engineering majors will definitely have a great advantage if they can speak German. German is rigorous, with moderate difficulty, which makes it easier to find a job.
French and Spanish are the best small languages for employment at present, but French goes to Africa and Spanish goes to Latin America. The difficulty is above average.
Korean, a good job, is not too difficult to learn, but I always feel that I speak too few countries and feel insecure.
Italian, Portuguese, similar to those European languages.
The remaining small languages are basically only available in a few schools, such as Beiwai Shangwai, Peking University Guangwai, Xiwai Chuantianwai, etc., and they are not enrolled every year, depending on your province and the year of college entrance examination. For example, the Indonesian language in Shanghai is enrolled every other year, and the Sanskrit Pali language in Peking University has only recruited four students since the founding of the People's Republic of China, and it has been approved in advance, recommended by 17 Foreign Language School.
