Which of the three languages, German, Russian and Japanese, has greater employment potential,

I think it's Russian, because there are too many people studying Japanese, and Sino-Japanese relations are too subtle, and the employment path in German is too narrow. Russian is different. There are not many people studying Russian now, and Sino-Russian friendly relations are developing steadily. Some well-known domestic enterprises such as Haier and Hisense are exploring the Russian market, and Wenzhou's small commodity base is even more optimistic about the Russian market.
