In China, in addition to English, the minor languages ??with the largest number of foreign-related patents should be: Japanese and German. These two small languages ??involve a large amount of them, and there are also a very small amount of French, Korean, etc., which are quite small and out of place.
What does it mean to have a large volume? That is to say, if you open a foreign-related agency and only do German or Japanese, if you are very, very good, you can theoretically expand your Japanese business to a medium scale or a large one. The German language institute is small and medium-sized.
Relatively speaking, the number of cases in Japanese is larger than that in German.
In terms of personnel saturation, the most scarce thing at present should be German-speaking talents, and there are relatively more Japanese-speaking talents than German-speaking talents.
When it comes to foreign affairs, English is always the king. This is undisputed.
Although many companies can quickly provide English translations of German/Japanese original texts, German and Japanese talents are also very promising. This demand should exist for a long time. The most promising one is Bilingual talents in English and German or English and Japanese (of course, it would be great if you are proficient in all three languages).
