In the past, when we wanted to learn a foreign language, we definitely had to buy a book called a "dictionary". But now, as time and technology advances, if we want to learn a foreign language, we don't need to bother buying and reading a dictionary. Because now social media, social media platforms and even online dictionaries can teach us to learn foreign languages. In fact, I think it's quicker and easier to understand. And I feel that way right now.
