I think this mainly depends on our working environment and work needs to decide how to invest in foreign languages. If our working environment rarely uses foreign languages to make friends, then we don't have to consider investing in this research. If we encounter foreign languages very frequently at work, or have certain exchanges with foreign trade, we can invest in English, such as learning some daily English and upgrading our business to English and international trade, especially English, which will greatly improve and draw lessons from our future work.
