Mandarin Chinese
Chinese should obviously be included on this list as it is the most frequently spoken language in the world, with 1.2 billion people speaking it in some form. Even though Chinese has many dialects, all of them use the same writing system, thus learning one will still enable you to communicate with speakers of other dialects via written words.
Chinese is sometimes regarded as one of the hardest languages to learn, therefore it's crucial to pick a great program that provides plenty of practice opportunities. Learning Chinese is a worthy effort because of the rising value of the language in the business world. The most popular choice for those who want to learn Chinese is Mandarin, a dialect of the language that is also the official state language of China. By studying Mandarin, you may communicate with millions of people globally, especially those who work in China's vast and growing economy.
