Besides English, what other foreign languages will make more people learn?

As far as population is concerned, French and Spanish are outside English. From the perspective of the future, I also want to know what language skills are the most promising (money) (⊙ _ ⊙). The world is developing so fast that the situation is changing every minute. Now this broken industry may gradually decline, and it is unknown whether it will become popular in the next second. It is best to learn a foreign language from the intention of career development combined with your own interests. After all, this is not an easy thing. Determination, perseverance and motivation are very important.

Judging from the recent situation, in foreign trade, it should be to learn Southeast Asian languages and Arabic. Most of these countries have import and export transactions with China. Then I said before that there may be frequent exchanges with Germany in some industries. Germany is a powerful country in science and technology, such as automobile and other industries, and the prospect of German should be good. I'm not familiar with this. This topic can be searched on Zhihu.

But I personally feel that some languages, such as French and Japanese, can stand the test of time forever and are personal lifelong wealth. Spanish-from the perspective of culture and number of users. Language is beautiful. Especially French, it is said that learning French and introducing other Latin languages: Spanish and Italian will also save a lot of effort. But any language needs lifelong learning, so it is very important to input and output regularly and quantitatively so as not to be unfamiliar. The machine should also be oiled frequently to avoid rusting. Language acquisition is very different from other skills. For example, learning to ride a bike is a lifelong muscle memory, but language is not. Therefore, learning a language seriously is a very serious thing, if you really want to achieve something.

To sum up, choose a language according to your own needs, and after you make up your mind, you will suffer. The gains will go beyond learning the language itself. The acquisition of language itself is already a huge wealth and the key to open the door to another world.
